Broken after upgrade

I am left today, after an upgrade I think (Fedora 23 --> 24) with a
broken postgresql.

It used to work very well. The service is started with the systemd
unit file. I have now this error:

-----------------
postgres@thetradinghall ➤➤ systemd/system %
/usr/libexec/postgresql-ctl start -D /db/pgsql/data -s -w -t 270
FATAL: 22023: database files are incompatible with server
DETAIL: The data directory was initialized by PostgreSQL version 9.4,
which is not compatible with this version 9.5.3.
-----------------------

Googling it gave me some entries, but I couldn't find any clear
explanation and how to solve. It seems I need to initiate a new
database, but thereafter is not clear (how to use my old data and conf
files pg_hba and pg_ident).

Thank you for hints/links how to solve this issue.

First, if possible copy your data dir and conf files somewhere for safety.

From the looks of it Fedora upgraded your Postgres from 9.4.x to 9.5.3.
That constitutes a major upgrade and as the error says the data
directory is no longer compatible.

What Postgres versions are installed?

Or did Fedora get rid of the Postgres 9.4 entirely?

I do not use Fedora so I cannot get any more specific but this might
help( I would still backup up your data directory manually, even if the
instructions below say that is done for you):

pretty much whatever you do, you'll need to install the 9.4 database
server software temporarily in a separate directory, and you'll need to
do the upgrade.

if your data is reasonable sized (say, under a few dozen gigabytes?),
the easiest upgrade is to fire up both servers (configure that 9.4 to
use a different port, like 5434), where 9.4 is running with your
existing data directory, and 9.5 is running a freshly initdb'd empty
database cluster, then do something like pg_dumpall -p 5434 | psql -p 5432

if the data is larger, that could take a really long time, so you'll
want to do a pg_upgrade, again with 9.4 configured for the existing
database, and 9.5 running on an empty new cluster, then follow the
pg_upgrade instructions on the website links above. this goes much
faster if both 'data' directories are on the same file system, and you
use the 'links' option...

I can read here[0]https://www.postgresql.org/docs/9.5/static/release-9-5.html on postgresql website that 9.5 have major enhancements.

Yes. I am only left with 9.5.3

pretty much whatever you do, you'll need to install the 9.4 database server

So the idea is to downgrade first to 9.4.8 ? I will try this way

My data are small hopefully.

no, not downgrade, you need both sets of code. install 9.4 (from the
PGDG yum repository) separately. the PGDG 9.4 code should go into
/usr/pgsql/9.4 and it will by default look for its data in
/var/lib/pgsql/9.4/data (so move your data directory to that...)

Take a look at this link:

It seems to offer a built in way to do this.

easiest upgrade is to fire up both servers (configure that 9.4 to use a

Re: Broken after upgrade

Hi,

Fedora packages have an executable (not sure about its name, but check a package called postgresql-upgrade or so). That will help you to finish the upgrade process.

Hello

Yes, the package is called postgresql-upgrade, and you can read detailed
instructions in /usr/share/doc/postgresql

In Fedora 22 (the machine i can check now) the document is called
README.rpm-dist in that directory

Hope helps you

I effectively found the postgresql-update tool. But when running it, I
get an error:

untouched after the init command. Is it correct ?

The above command returns an error:

when running pg_upgrade, where is the socket ? I guess it shall be in

can I change this behavior? How can I tell pg_upgrade to place the

Running the following command (it indicates where to find the socket):

"pg_upgrade_server.log" -D "/db/pgsql/data.old" -o "-p 50432 -b -c

leave me this time with another error, in fact the original one:

DETAIL: The data directory was initialized by PostgreSQL version 9.5,

So aside this socket issue, it seems I am back again to the
initialization issue. Is there something wrong in the command I use ?

My postgresql service is in fact started with its socket in

when running pg_upgrade, where is the socket ? I guess it shall be in
<< unix_socket_directories='/db/pgsql' >> as indicated in the log file
above? But it isn't apparently as postgresql can find the socket. How
can I change this behavior? How can I tell pg_upgrade to place the
socket in /db/pgsql ?

Thank you for help. This issue is getting me crazy and my mail server is broken.

UPDATE

Running the following command (it indicates where to find the socket):

$ /usr/lib64/pgsql/postgresql-9.4/bin/pg_ctl -w -l
"pg_upgrade_server.log" -D "/db/pgsql/data.old" -o "-p 50432 -b -c
listen_addresses='' -c unix_socket_permissions=0700 -c

leave me this time with another error, in fact the original one:

% cat pg_upgrade_server.log

DETAIL: The data directory was initialized by PostgreSQL version 9.5,
which is not compatible with this version 9.4.8.

Actually it is the opposite of your original message:

"postgres(at)thetradinghall ➤➤ systemd/system %
/usr/libexec/postgresql-ctl start -D /db/pgsql/data -s -w -t 270
FATAL: 22023: database files are incompatible with server
DETAIL: The data directory was initialized by PostgreSQL version 9.4,
which is not compatible with this version 9.5.3.

So aside this socket issue, it seems I am back again to the
initialization issue. Is there something wrong in the command I use ?

$ pg_upgrade -b /usr/lib64/pgsql/postgresql-9.4/bin/ -B /usr/bin -d
/db/pgsql/data.old -D /db/pgsql/data

Have no idea as I am confused as to your layout and what you have done, so:

1) Did you run the Fedora postgresql-setup upgrade command at any time?

2) What versions of Postgres do you have installed and/or running?
Please verify from package manager and/or ps.

3) List what is in the PG_VERSION file of each directory you are using.

Hello

Yes, the package is called postgresql-upgrade, and you can read

In Fedora 22 (the machine i can check now) the document is called
README.rpm-dist in that directory

Hope helps you

I effectively found the postgresql-update tool. But when running it, I

It took me some time to figure out the correct way for Fedora to

user, with postgresql.service stopped:

$ pg_upgrade -b /usr/lib64/pgsql/postgresql-9.4/bin/ -B /usr/bin -d

with data a new DB initialized with postgresql 9.5, data.old my

NOTE: I didn't put my original config files pg_hba.conf, pg_ident.conf

untouched after the init command. Is it correct ?

The above command returns an error:

Have no idea as I am confused as to your layout and what you have done, so:

I understand you are confused, as I am too and tried too many things
with no success.

I have postgresql 9.5.3 installed, and the upgrade was from 9.4.8 to 9.5.3.
I can find in /usr/lib64/pgsql/postgresql-9.4 some binaries from
previous versions. Nothing in /opt/ as it can be sometimes indicated.

I have my old database in /db/pgsql/data.old and the new empty
initialized with 9.5 in /db/pgsql/data.old (here versions are given by
PG_VERSION files).

1) Did you run the Fedora postgresql-setup upgrade command at any time?

Yes I did many times against a /db/pgsql/data with my 9.4 database (If
I run the command with the 9.5 initialized data folder, I get ERROR:

Hi,

Hello

Yes, the package is called postgresql-upgrade, and you can read
detailed
instructions in /usr/share/doc/postgresql

In Fedora 22 (the machine i can check now) the document is called
README.rpm-dist in that directory

Hope helps you

I effectively found the postgresql-update tool. But when running it, I
get an error:

# postgresql-setup --upgrade

* Upgrading database.
ERROR: pg_upgrade tool failed
ERROR: Upgrade failed.
* See /var/lib/pgsql/upgrade_postgresql.log for details.

--------------------------------------------------

My data dir is in fact /db/pgsql/data. I do not know why it is looking
for data-old.
I will investigate this way.

It took me some time to figure out the correct way for Fedora to
upgrade pgsql. Here is the command I am supposed to run as postgres
user, with postgresql.service stopped:

$ pg_upgrade -b /usr/lib64/pgsql/postgresql-9.4/bin/ -B /usr/bin -d
/db/pgsql/data.old -D /db/pgsql/data

with data a new DB initialized with postgresql 9.5, data.old my
original DB, postgresql-9.4/bin old cluster executable.
NOTE: I didn't put my original config files pg_hba.conf, pg_ident.conf
and postgresql.conf in the new data directory. I left everything
untouched after the init command. Is it correct ?

The above command returns an error:
-----------------------------------------------------------------------
*failure*
Consult the last few lines of "pg_upgrade_server.log" for
the probable cause of the failure.

connection to database failed: could not connect to server: No such

---------------------------------------------------------------------

My postgresql service is in fact started with its socket in
/run/postgresql directory, as indicated in my postgresql.conf. Now,
when running pg_upgrade, where is the socket ? I guess it shall be in
<< unix_socket_directories='/db/pgsql' >> as indicated in the log file
above? But it isn't apparently as postgresql can find the socket. How
can I change this behavior? How can I tell pg_upgrade to place the
socket in /db/pgsql ?

Thank you for help. This issue is getting me crazy and my mail server is
broken.

UPDATE

Running the following command (it indicates where to find the socket):

$ /usr/lib64/pgsql/postgresql-9.4/bin/pg_ctl -w -l
"pg_upgrade_server.log" -D "/db/pgsql/data.old" -o "-p 50432 -b -c
listen_addresses='' -c unix_socket_permissions=0700 -c
unix_socket_directories='/run/postgresql'" start >>
"pg_upgrade_server.log"

leave me this time with another error, in fact the original one:

% cat pg_upgrade_server.log
waiting for server to start....FATAL: 22023: database files are
incompatible with server
DETAIL: The data directory was initialized by PostgreSQL version 9.5,
which is not compatible with this version 9.4.8.

Actually it is the opposite of your original message:

"postgres(at)thetradinghall ➤➤ systemd/system %
/usr/libexec/postgresql-ctl start -D /db/pgsql/data -s -w -t 270
FATAL: 22023: database files are incompatible with server
DETAIL: The data directory was initialized by PostgreSQL version 9.4,
which is not compatible with this version 9.5.3.

So aside this socket issue, it seems I am back again to the
initialization issue. Is there something wrong in the command I use ?

$ pg_upgrade -b /usr/lib64/pgsql/postgresql-9.4/bin/ -B /usr/bin -d
/db/pgsql/data.old -D /db/pgsql/data

Have no idea as I am confused as to your layout and what you have done, so:

I understand you are confused, as I am too and tried too many things
with no success.

I have postgresql 9.5.3 installed, and the upgrade was from 9.4.8 to 9.5.3.
I can find in /usr/lib64/pgsql/postgresql-9.4 some binaries from
previous versions. Nothing in /opt/ as it can be sometimes indicated.

I have my old database in /db/pgsql/data.old and the new empty
initialized with 9.5 in /db/pgsql/data.old (here versions are given by
PG_VERSION files).

The above does not make sense, they both cannot be in the same data
directory. So to repeat, please answer each of the below after the
question and in detail eg. showing the actual commands you ran and the
results:

2) What versions of Postgres do you have installed and/or running?
Please verify from package manager and/or ps.

3) List what is in the PG_VERSION file of each directory you are using.

1) Did you run the Fedora postgresql-setup upgrade command at any time?

Yes I did many times against a /db/pgsql/data with my 9.4 database (If
I run the command with the 9.5 initialized data folder, I get ERROR:
Cannot upgrade because the database in /db/pgsql/data is of
version 9.5 but it should be 9.4).

The command failed with this error:

--------------------------
*failure*

the probable cause of the failure.

----------------------------

As already mentioned, postgresql put its socket in /run/postgresql.
Btw, both directories (/run/postgresql and /home/postgresql) are
indicated in postgresql.conf:
unix_socket_directories = '/home/postgres,/run/postgresql'

I would like now to try the above command when avoiding this socket story issue.

2) What versions of Postgres do you have installed and/or running?
