From 0ef06b0c50c882f418ca9d71fe53e0570738b3a6 Mon Sep 17 00:00:00 2001
From: Andres Freund <andres@anarazel.de>
Date: Fri, 28 Sep 2018 15:13:42 -0700
Subject: [PATCH v1 1/2] Remove timetravel extension.

The extension depended on old types which are about to be removed. As
the code additionally was pretty crufty and didn't provide that much
in the way of features, removing the extension seems to be the best
way forward.

-  <title>timetravel &mdash; Functions for Implementing Time Travel</title>
-
-  <para>
-   Long ago, <productname>PostgreSQL</productname> had a built-in time travel feature
-   that kept the insert and delete times for each tuple.  This can be
-   emulated using these functions.  To use these functions,
-   you must add to a table two columns of <type>abstime</type> type to store
-   the date when a tuple was inserted (start_date) and changed/deleted
-   (stop_date):
-
-<programlisting>
-CREATE TABLE mytab (
-        ...             ...
-        start_date      abstime,
-        stop_date       abstime
-        ...             ...
-);
-</programlisting>
-
-   The columns can be named whatever you like, but in this discussion
-   we'll call them start_date and stop_date.
-  </para>
-
-  <para>
-   When a new row is inserted, start_date should normally be set to
-   current time, and stop_date to <literal>infinity</literal>.  The trigger
-   will automatically substitute these values if the inserted data

-   Tuples with stop_date equal to <literal>infinity</literal> are <quote>valid

-   to do that, you can turn off time travel as shown below.)

-  <para>
-   For a modifiable row, on update only the stop_date in the tuple being
-   updated will be changed (to current time) and a new tuple with the modified
-   data will be inserted.  Start_date in this new tuple will be set to current
-   time and stop_date to <literal>infinity</literal>.

-   To query for tuples <quote>valid now</quote>, include

-   <function>timetravel()</function> is the general trigger function that supports

-   trigger using this function on each time-traveled table. Specify two
-   trigger arguments: the actual
-   names of the start_date and stop_date columns.
-   Optionally, you can specify one to three more arguments, which must refer
-   to columns of type <type>text</type>.  The trigger will store the name of
-   the current user into the first of these columns during INSERT, the
-   second column during UPDATE, and the third during DELETE.
-  </para>
-
-  <para>
-   <function>set_timetravel()</function> allows you to turn time-travel on or off for
-   a table.
-   <literal>set_timetravel('mytab', 1)</literal> will turn TT ON for table <literal>mytab</literal>.
-   <literal>set_timetravel('mytab', 0)</literal> will turn TT OFF for table <literal>mytab</literal>.
-   In both cases the old status is reported.  While TT is off, you can modify
-   the start_date and stop_date columns freely.  Note that the on/off status
-   is local to the current database session &mdash; fresh sessions will
-   always start out with TT ON for all tables.

From ec3dbb32edaedec54fbab25c1dc607c935f162ca Mon Sep 17 00:00:00 2001
From: Andres Freund <andres@anarazel.de>
Date: Fri, 28 Sep 2018 15:21:48 -0700
Subject: [PATCH v1 2/2] Remove deprecated abstime, reltime, tinterval
 datatypes and timeofday().

These types have been deprecated for a *long* time, and their code has
not magically gotten better.

The timeofday function was implemented in removed code, as seems
sufficiently weird (returning text) that moving it elsewhere is not
worthwhile.
