WIP: Avoid creation of the free space map for small tables

Subject: [PATCH v2] Avoid creation of the free space map for small tables.

The FSM isn't created if the heap has fewer than 10 blocks. If the last
known good block has insufficient space, try every block before extending
the heap.

If a heap with a FSM is truncated back to below the threshold, the FSM
stays around and can be used as usual.

If the heap tuples are all deleted, the FSM stays but has no leaf blocks
(same as before). Although it exists, it won't be re-extended until
the heap passes the threshold again.

From f3abe9fc003430530db71ddd40c4e9bed8a38513 Mon Sep 17 00:00:00 2001

Subject: [PATCH v4] Avoid creation of the free space map for small tables.

The FSM isn't created if the heap has fewer than 10 blocks. If the last
known good block has insufficient space, try every block before extending
the heap.

If a heap with a FSM is truncated back to below the threshold, the FSM
stays around and can be used as usual.

From 0dafd220e437ed1cf9ed77e41cf3090365a63798 Mon Sep 17 00:00:00 2001
From: John Naylor <jcnaylor@gmail.com>
Date: Tue, 16 Oct 2018 17:10:14 +0700
Subject: [PATCH v5 1/2] Avoid creation of the free space map for small tables.

The FSM isn't created if the heap has fewer than 10 blocks. If the last
known good block has insufficient space, try every block before extending
the heap.

If a heap with a FSM is truncated back to below the threshold, the FSM
stays around and can be used as usual.

From b928d4fd814aefaa90bde5388ad81a1a68e363a5 Mon Sep 17 00:00:00 2001
From: John Naylor <jcnaylor@gmail.com>
Date: Tue, 16 Oct 2018 17:12:19 +0700
Subject: [PATCH v5 2/2] Add parameter nblocks to RecordPageWithFreeSpace().

Now, VACUUM won't be penalized by too many system calls to get number of
blocks in the relation when it calls RecordPageWithFreeSpace().

From 529fa1f57946d70736b2304c2883213e45f7c077 Mon Sep 17 00:00:00 2001

Subject: [PATCH v6] Avoid creation of the free space map for small tables.

The FSM isn't created if the heap has fewer than 8 blocks. If the last
known good block has insufficient space, try every block before extending
the heap.

If a heap with a FSM is truncated back to below the threshold, the FSM
stays around and can be used as usual.

From 428b56e12e3f5d2bd8fc81c9fb5fe7169e9da580 Mon Sep 17 00:00:00 2001
From: John Naylor <jcnaylor@gmail.com>
Date: Wed, 31 Oct 2018 14:26:38 +0700
Subject: [PATCH v7 1/2] Avoid creation of the free space map for small tables.

The FSM isn't created if the heap has fewer than 8 blocks. If the last
known good block has insufficient space, try every block before extending
the heap.

If a heap with a FSM is truncated back to below the threshold, the FSM
stays around and can be used as usual.

Subject: [PATCH v8 2/3] Avoid creation of the free space map for small tables.

The FSM isn't created if the heap has 4 blocks or fewer. If the last
known target block has insufficient space, try every block before extending
the heap.

If a heap with a FSM is truncated back to below the threshold, the FSM
stays around and can be used as usual.

From c4bef3bf790745638d42e5eb6b303b85a9a828c4 Mon Sep 17 00:00:00 2001

Subject: [PATCH v9 1/2] Avoid creation of the free space map for small tables.

The FSM isn't created if the heap has 4 blocks or fewer. If the last
known target block has insufficient space, try every block before extending
the heap.

If a heap with a FSM is truncated back to below the threshold, the FSM
stays around and can be used as usual.

From 7494ff89be7ad4e07f277f3bcc6e866c5527ce45 Mon Sep 17 00:00:00 2001
From: John Naylor <jcnaylor@gmail.com>
Date: Thu, 6 Dec 2018 10:49:03 -0600
Subject: [PATCH v10 1/2] Avoid creation of the free space map for small
 tables.

The FSM isn't created if the heap has 4 blocks or fewer. If the last
known target block has insufficient space, try every block before extending
the heap.

If a heap with a FSM is truncated back to below the threshold, the FSM
stays around and can be used as usual.

From ab1ced145c43b0adadd9b1219ceaeb3553885e08 Mon Sep 17 00:00:00 2001
From: Amit Kapila <akapila@postgresql.org>
Date: Sat, 8 Dec 2018 18:30:43 +0530
Subject: [PATCH] Avoid creation of the free space map for small tables.

The FSM isn't created if the heap has 4 blocks or fewer. If the last
known target block has insufficient space, try every block before extending
the heap.

If a heap with a FSM is truncated back to below the threshold, the FSM
stays around and can be used as usual.

Subject: [PATCH v12 1/2] Avoid creation of the free space map for small heap
 relations.

Previously, all heaps had FSMs. For very small tables, this means that
the FSM took up more space than the heap did. This is wasteful, so now
we refrain from creating the FSM for heaps with 4 pages or fewer. If the
last known target block has insufficient space, we still try to insert
into some other page before before giving up and extending the relation,
since doing otherwise leads to table bloat. Testing showed that trying
every page penalized performance slightly, so we compromise and try
every other page. This way, we visit at most two pages. Any pages with
wasted free space become visible at next relation extension, so we still
control table bloat. As a bonus, directly attempting one or two pages
can even be faster than consulting the FSM would have been.

If a heap with a FSM is truncated back to below the threshold, the FSM
stays around and can be used as usual.

+fixed-size FSM.  There are two exceptions:
+
+1. Hash indexes never have a FSM.
+2. For very small heap relations, the FSM would be relatively large and
+wasteful, so as of PostgreSQL 12 we refrain from creating the FSM for
+heaps with HEAP_FSM_CREATION_THRESHOLD pages or fewer, both to save space
+and to improve performance.  To locate free space in this case, we simply
+iterate over the heap, trying alternating pages in turn.  There may be some
+wasted free space in this case, but it becomes visible again upon next
+relation extension.
 
 It is important to keep the map small so that it can be searched rapidly.
 Therefore, we don't attempt to record the exact free space on a page.

Subject: [PATCH v12 2/2] During pg_upgrade, conditionally skip transfer of
 FSMs.

If a heap on the old cluster has 4 pages or fewer, don't copy or
link the FSM. This will reduce space usage for installations with
large numbers of small tables.

From e7272422fb9bfa4f65ec2ccbab460eb54afac298 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Avoid creation of the free space map for small heap
 relations.

Previously, all heaps had FSMs. For very small tables, this means that
the FSM took up more space than the heap did. This is wasteful, so now
we refrain from creating the FSM for heaps with 4 pages or fewer. If the
last known target block has insufficient space, we still try to insert
into some other page before before giving up and extending the relation,
since doing otherwise leads to table bloat. Testing showed that trying
every page penalized performance slightly, so we compromise and try
every other page. This way, we visit at most two pages. Any pages with
wasted free space become visible at next relation extension, so we still
control table bloat. As a bonus, directly attempting one or two pages
can even be faster than consulting the FSM would have been.

From 38bc2d9b4ae3f0d1ab6d21c54ed638c5aee6d637 Mon Sep 17 00:00:00 2001
From: John Naylor <jcnaylor@gmail.com>

Subject: [PATCH v14 1/2] Avoid creation of the free space map for small heap 
 relations.

Previously, all heaps had FSMs. For very small tables, this means that
the FSM took up more space than the heap did. This is wasteful, so now
we refrain from creating the FSM for heaps with 4 pages or fewer. If the
last known target block has insufficient space, we still try to insert
into some other page before before giving up and extending the relation,
since doing otherwise leads to table bloat. Testing showed that trying
every page penalized performance slightly, so we compromise and try
every other page. This way, we visit at most two pages. Any pages with
wasted free space become visible at next relation extension, so we still
control table bloat. As a bonus, directly attempting one or two pages
can even be faster than consulting the FSM would have been.

+fixed-size FSM.  There are two exceptions:
+
+1. Hash indexes never have a FSM.
+2. For very small tables, a 3-page relation fork would be relatively large
+and wasteful, so to save space we refrain from creating the FSM if the
+heap has HEAP_FSM_CREATION_THRESHOLD pages or fewer.
+
+To locate free space in the latter case, we simply try pages directly without
+knowing ahead of time how much free space they have.  To maintain good
+performance, we create a local in-memory map of pages to try, and only mark
+every other page as available.  For example, in a 3-page heap:
+
+ANAN
+0123
+
+Pages 0 and 2 are marked "available", and page 1 as "not available".
+Page 3 is beyond the end of the relation, so is likewise marked "not
+available".  First we try page 2, and if that doesn't have sufficient free
+space we try page 0 before giving up and extending the relation.  There may
+be some wasted free space on block 1, but if the relation extends to 4 pages:
+
+NANA
+0123
+
+We not only have the new page 3 at our disposal, we can now check page 1
+for free space as well.

Subject: [PATCH v14 2/2] During pg_upgrade, conditionally skip transfer of 
 FSMs.

If a heap on the old cluster has 4 pages or fewer, don't copy or
link the FSM. This will reduce space usage for installations with
large numbers of small tables.

From 11dfb805e03bc7e144fd137ef6dc6601ff728d3a Mon Sep 17 00:00:00 2001

Subject: [PATCH] Avoid creation of the free space map for small heap
 relations.

Previously, all heaps had FSMs. For very small tables, this means that
the FSM took up more space than the heap did. This is wasteful, so now
we refrain from creating the FSM for heaps with 4 pages or fewer. If the
last known target block has insufficient space, we still try to insert
into some other page before before giving up and extending the relation,
since doing otherwise leads to table bloat. Testing showed that trying
every page penalized performance slightly, so we compromise and try
every other page. This way, we visit at most two pages. Any pages with
wasted free space become visible at next relation extension, so we still
control table bloat. As a bonus, directly attempting one or two pages
can even be faster than consulting the FSM would have been.

+Each heap relation, unless it is very small, and each index relation, except
+for hash indexes, has a Free Space Map (FSM) to keep track of available
+space in the relation. It's stored alongside the main relation data in a
+separate relation fork, named after the filenode number of the relation, plus
+a <literal>_fsm</literal> suffix. For example, if the filenode of a relation
+is 12345, the FSM is stored in a file called <filename>12345_fsm</filename>,

+fixed-size FSM.  There are two exceptions:
+
+1. Hash indexes never have a FSM.
+2. For very small tables, a 3-page relation fork would be relatively large
+and wasteful, so to save space we refrain from creating the FSM if the
+heap has HEAP_FSM_CREATION_THRESHOLD pages or fewer.
+
+To locate free space in the latter case, we simply try pages directly without
+knowing ahead of time how much free space they have.  To maintain good
+performance, we create a local in-memory map of pages to try, and only mark
+every other page as available.  For example, in a 3-page heap, the local map
+would look like:
+
+ANAN
+0123
+
+Pages 0 and 2 are marked "available", and page 1 as "not available".
+Page 3 is beyond the end of the relation, so is likewise marked "not
+available".  First we try page 2, and if that doesn't have sufficient free
+space we try page 0 before giving up and extending the relation.  There may
+be some wasted free space on block 1, but if the relation extends to 4 pages:
+
+NANA
+0123
+
+We not only have the new page 3 at our disposal, we can now check page 1

From ecf0cecee8b0adf8529ddb1fbdabd041172de5e3 Mon Sep 17 00:00:00 2001
From: John Naylor <jcnaylor@gmail.com>
Date: Sat, 19 Jan 2019 18:39:39 -0500
Subject: [PATCH v16 1/2] Avoid creation of the free space map for small heap
 relations.

Previously, all heaps had FSMs. For very small tables, this means that
the FSM took up more space than the heap did. This is wasteful, so now
we refrain from creating the FSM for heaps with 4 pages or fewer. If the
last known target block has insufficient space, we still try to insert
into some other page before before giving up and extending the relation,
since doing otherwise leads to table bloat. Testing showed that trying
every page penalized performance slightly, so we compromise and try
every other page. This way, we visit at most two pages. Any pages with
wasted free space become visible at next relation extension, so we still
control table bloat. As a bonus, directly attempting one or two pages
can even be faster than consulting the FSM would have been.

+fixed-size FSM.  There are two exceptions:
+
+1. Hash indexes never have a FSM.
+2. For very small tables, a 3-page relation fork would be relatively large
+and wasteful, so to save space we refrain from creating the FSM if the
+heap has HEAP_FSM_CREATION_THRESHOLD pages or fewer.
+
+To locate free space in the latter case, we simply try pages directly without
+knowing ahead of time how much free space they have.  To maintain good
+performance, we create a local in-memory map of pages to try, and only mark
+every other page as available.  For example, in a 3-page heap, the local map
+would look like:
+
+ANAN
+0123
+
+Pages 0 and 2 are marked "available", and page 1 as "not available".
+Page 3 is beyond the end of the relation, so is likewise marked "not
+available".  First we try page 2, and if that doesn't have sufficient free
+space we try page 0 before giving up and extending the relation.  There may
+be some wasted free space on block 1, but if the relation extends to 4 pages:

+NANA

+
+We not only have the new page 3 at our disposal, we can now check page 1

Subject: [PATCH v16 2/2] During pg_upgrade, conditionally skip transfer of
 FSMs.

If a heap on the old cluster has 4 pages or fewer, don't copy or
link the FSM. This will reduce space usage for installations with
large numbers of small tables.

Subject: [PATCH 1/2] In bootstrap mode, don't allow the creation of files if
 they don't already exist.

In commit's b9d01fe288 and 3908473c80, we have added some code where we
allowed the creation of files during mdopen even if they didn't exist
during the bootstrap mode.  The later commit obviates the need for same.

This was harmless code till now but with an upcoming feature where we don't
allow to create FSM for small tables, this will needlessly create FSM files.

Subject: [PATCH 2/2] Avoid creation of the free space map for small heap
 relations.

Previously, all heaps had FSMs. For very small tables, this means that the
FSM took up more space than the heap did. This is wasteful, so now we
refrain from creating the FSM for heaps with 4 pages or fewer. If the last
known target block has insufficient space, we still try to insert into some
other page before giving up and extending the relation, since doing
otherwise leads to table bloat. Testing showed that trying every page
penalized performance slightly, so we compromise and try every other page.
This way, we visit at most two pages. Any pages with wasted free space
become visible at next relation extension, so we still control table bloat.
As a bonus, directly attempting one or two pages can even be faster than
consulting the FSM would have been.

Once the FSM is created for heap we don't remove it even if somebody
deletes all the rows from the corresponding relation.  We don't think it is a
useful optimization as it is quite likely that relation will again grow to the
same size.

 exists and the relation must be extended by one page.  As of PostgreSQL 8.4
 each relation has its own, extensible free space map stored in a separate
 "fork" of its relation.  This eliminates the disadvantages of the former
-fixed-size FSM.
+fixed-size FSM.  There are two exceptions:
+
+1. Hash indexes never have a FSM.
+2. For very small tables, a 3-page relation fork would be relatively large
+and wasteful, so to save space we refrain from creating the FSM if the
+heap has HEAP_FSM_CREATION_THRESHOLD pages or fewer.
+
+To locate free space in the latter case, we simply try pages directly without
+knowing ahead of time how much free space they have.  To maintain good
+performance, we create a local in-memory map of pages to try, and only mark
+every other page as available.  For example, in a 3-page heap, the local map
+would look like:
+
+ANAN
+0123
+
+Pages 0 and 2 are marked "available", and page 1 as "not available".
+Page 3 is beyond the end of the relation, so is likewise marked "not
+available".  First we try page 2, and if that doesn't have sufficient free
+space we try page 0 before giving up and extending the relation.  There may
+be some wasted free space on block 1, but if the relation extends to 4 pages:
+
+NANA
+0123
+
+We not only have the new page 3 at our disposal, we can now check page 1
+for free space as well.
+
+Once the FSM is created for heap we don't remove it even if somebody deletes
+all the rows from the corresponding relation.  We don't think it is a useful

Subject: [PATCH 2/2] Avoid creation of the free space map for small heap
 relations.

Previously, all heaps had FSMs. For very small tables, this means that the
FSM took up more space than the heap did. This is wasteful, so now we
refrain from creating the FSM for heaps with 4 pages or fewer. If the last
known target block has insufficient space, we still try to insert into some
other page before giving up and extending the relation, since doing
otherwise leads to table bloat. Testing showed that trying every page
penalized performance slightly, so we compromise and try every other page.
This way, we visit at most two pages. Any pages with wasted free space
become visible at next relation extension, so we still control table bloat.
As a bonus, directly attempting one or two pages can even be faster than
consulting the FSM would have been.

Once the FSM is created for a heap we don't remove it even if somebody
deletes all the rows from the corresponding relation.  We don't think it is
a useful optimization as it is quite likely that relation will again grow to
the same size.

 each relation has its own, extensible free space map stored in a separate
 "fork" of its relation.  This eliminates the disadvantages of the former
-fixed-size FSM.
+fixed-size FSM.  There are two exceptions:
+
+1. Hash indexes never have a FSM.
+2. For very small tables, a 3-page relation fork would be relatively large
+and wasteful, so to save space we refrain from creating the FSM if the
+heap has HEAP_FSM_CREATION_THRESHOLD pages or fewer.
+
+To locate free space in the latter case, we simply try pages directly without
+knowing ahead of time how much free space they have.  To maintain good
+performance, we create a local in-memory map of pages to try, and only mark
+every other page as available.  For example, in a 3-page heap, the local map
+would look like:
+
+ANAN
+0123
+
+Pages 0 and 2 are marked "available", and page 1 as "not available".
+Page 3 is beyond the end of the relation, so is likewise marked "not
+available".  First we try page 2, and if that doesn't have sufficient free
+space we try page 0 before giving up and extending the relation.  There may
+be some wasted free space on block 1, but if the relation extends to 4 pages:
+
+NANA
+0123
+
+We not only have the new page 3 at our disposal, we can now check page 1
+for free space as well.
+
+Once the FSM is created for a heap we don't remove it even if somebody deletes
+all the rows from the corresponding relation.  We don't think it is a useful
+optimization as it is quite likely that relation will again grow to the same
+size.
+
+FSM data structure
+------------------
 
 It is important to keep the map small so that it can be searched rapidly.
 Therefore, we don't attempt to record the exact free space on a page.

Subject: [PATCH 1/2] In bootstrap mode, don't allow the creation of files if
 they don't already exist.

In commit's b9d01fe288 and 3908473c80, we have added some code where we
allowed the creation of files during mdopen even if they didn't exist
during the bootstrap mode.  The later commit obviates the need for same.

This was harmless code till now but with an upcoming feature where we don't
allow to create FSM for small tables, this will needlessly create FSM files.

From 277d969c31349b22e2c7726935d681e72aacaece Mon Sep 17 00:00:00 2001

Subject: [PATCH v19 3/3] During pg_upgrade, conditionally skip transfer of
 FSMs.

If a heap on the old cluster has 4 pages or fewer, don't copy or
link the FSM. This will reduce space usage for installations with
large numbers of small tables.

Subject: [PATCH v21 3/3] During pg_upgrade, conditionally skip transfer of
 FSMs.

If a heap on the old cluster has 4 pages or fewer, and the old cluster
was PG v11 or earlier, don't copy or link the FSM. This will shrink
space usage for installations with large numbers of small tables.

Subject: [PATCH 2/2] Avoid creation of the free space map for small heap
 relations.

Previously, all heaps had FSMs. For very small tables, this means that the
FSM took up more space than the heap did. This is wasteful, so now we
refrain from creating the FSM for heaps with 4 pages or fewer. If the last
known target block has insufficient space, we still try to insert into some
other page before giving up and extending the relation, since doing
otherwise leads to table bloat. Testing showed that trying every page
penalized performance slightly, so we compromise and try every other page.
This way, we visit at most two pages. Any pages with wasted free space
become visible at next relation extension, so we still control table bloat.
As a bonus, directly attempting one or two pages can even be faster than
consulting the FSM would have been.

Once the FSM is created for a heap we don't remove it even if somebody
deletes all the rows from the corresponding relation.  We don't think it is
a useful optimization as it is quite likely that relation will again grow to
the same size.

+fixed-size FSM.  There are two exceptions:
+
+1. Hash indexes never have a FSM.
+2. For very small tables, a 3-page relation fork would be relatively large
+and wasteful, so to save space we refrain from creating the FSM if the
+heap has HEAP_FSM_CREATION_THRESHOLD pages or fewer.
+
+To locate free space in the latter case, we simply try pages directly without
+knowing ahead of time how much free space they have.  To maintain good
+performance, we create a local in-memory map of pages to try, and only mark
+every other page as available.  For example, in a 3-page heap, the local map
+would look like:
+
+ANAN
+0123
+
+Pages 0 and 2 are marked "available", and page 1 as "not available".
+Page 3 is beyond the end of the relation, so is likewise marked "not
+available".  First we try page 2, and if that doesn't have sufficient free
+space we try page 0 before giving up and extending the relation.  There may
+be some wasted free space on block 1, but if the relation extends to 4 pages:
+
+NANA
+0123
+
+We not only have the new page 3 at our disposal, we can now check page 1
+for free space as well.
+
+Once the FSM is created for a heap we don't remove it even if somebody deletes
+all the rows from the corresponding relation.  We don't think it is a useful
+optimization as it is quite likely that relation will again grow to the same
+size.

 It is important to keep the map small so that it can be searched rapidly.
 Therefore, we don't attempt to record the exact free space on a page.

Subject: [PATCH] Avoid creation of the free space map for small heap
 relations.

Previously, all heaps had FSMs. For very small tables, this means that the
FSM took up more space than the heap did. This is wasteful, so now we
refrain from creating the FSM for heaps with 4 pages or fewer. If the last
known target block has insufficient space, we still try to insert into some
other page before giving up and extending the relation, since doing
otherwise leads to table bloat. Testing showed that trying every page
penalized performance slightly, so we compromise and try every other page.
This way, we visit at most two pages. Any pages with wasted free space
become visible at next relation extension, so we still control table bloat.
As a bonus, directly attempting one or two pages can even be faster than
consulting the FSM would have been.

Once the FSM is created for a heap we don't remove it even if somebody
deletes all the rows from the corresponding relation.  We don't think it is
a useful optimization as it is quite likely that relation will again grow
to the same size.

+fixed-size FSM.  There are two exceptions:
+
+1. Hash indexes never have a FSM.
+2. For very small tables, a 3-page relation fork would be relatively large
+and wasteful, so to save space we refrain from creating the FSM if the
+heap has HEAP_FSM_CREATION_THRESHOLD pages or fewer.
+
+To locate free space in the latter case, we simply try pages directly without
+knowing ahead of time how much free space they have.  To maintain good
+performance, we create a local in-memory map of pages to try, and only mark
+every other page as available.  For example, in a 3-page heap, the local map
+would look like:
+
+ANAN
+0123
+
+Pages 0 and 2 are marked "available", and page 1 as "not available".
+Page 3 is beyond the end of the relation, so is likewise marked "not
+available".  First we try page 2, and if that doesn't have sufficient free
+space we try page 0 before giving up and extending the relation.  There may
+be some wasted free space on block 1, but if the relation extends to 4 pages:
+
+NANA
+0123
+
+We not only have the new page 3 at our disposal, we can now check page 1
+for free space as well.
+
+Once the FSM is created for a heap we don't remove it even if somebody deletes
+all the rows from the corresponding relation.  We don't think it is a useful
+optimization as it is quite likely that relation will again grow to the same
+size.

 It is important to keep the map small so that it can be searched rapidly.
 Therefore, we don't attempt to record the exact free space on a page.

Subject: [PATCH] Avoid creation of the free space map for small heap
 relations.

Previously, all heaps had FSMs. For very small tables, this means that the
FSM took up more space than the heap did. This is wasteful, so now we
refrain from creating the FSM for heaps with 4 pages or fewer. If the last
known target block has insufficient space, we still try to insert into some
other page before giving up and extending the relation, since doing
otherwise leads to table bloat. Testing showed that trying every page
penalized performance slightly, so we compromise and try every other page.
This way, we visit at most two pages. Any pages with wasted free space
become visible at next relation extension, so we still control table bloat.
As a bonus, directly attempting one or two pages can even be faster than
consulting the FSM would have been.

Once the FSM is created for a heap we don't remove it even if somebody
deletes all the rows from the corresponding relation.  We don't think it is
a useful optimization as it is quite likely that relation will again grow
to the same size.

-fixed-size FSM.
+fixed-size FSM.  There are two exceptions:
+
+1. Hash indexes never have a FSM.
+2. For very small tables, a 3-page relation fork would be relatively large
+and wasteful, so to save space we refrain from creating the FSM if the
+heap has HEAP_FSM_CREATION_THRESHOLD pages or fewer.
+
+To locate free space in the latter case, we simply try pages directly without
+knowing ahead of time how much free space they have.  To maintain good
+performance, we create a local in-memory map of pages to try, and only mark
+every other page as available.  For example, in a 3-page heap, the local map
+would look like:
+
+ANAN
+0123
+
+Pages 0 and 2 are marked "available", and page 1 as "not available".
+Page 3 is beyond the end of the relation, so is likewise marked "not
+available".  First we try page 2, and if that doesn't have sufficient free
+space we try page 0 before giving up and extending the relation.  There may
+be some wasted free space on block 1, but if the relation extends to 4 pages:
+
+NANA
+0123
+
+We not only have the new page 3 at our disposal, we can now check page 1
+for free space as well.
+
+Once the FSM is created for a heap we don't remove it even if somebody deletes
+all the rows from the corresponding relation.  We don't think it is a useful
+optimization as it is quite likely that relation will again grow to the same
+size.
