Обсуждение: Upgrade from 8.4.13 to 9.2.0.1 successful but it still displays 8.4.13 if SELECT version();
Hi,
I have upgraded postgresql 8.4.13 to 9.2.0.1 O/S Ubuntu, restarted postgresql, it displayed my postgresql is 9.2 but
whenI log into postgresql, show version, it is still 8.4.13, see a) and b) below,
a)
* Restarting PostgreSQL 9.2 database server
...done.
b)
psql (8.4.13)
Type "help" for help.
postgres=# SELECT version();
version
--------------------------------------------------------------------------------------------------------------
PostgreSQL 8.4.13 on i486-pc-linux-gnu, compiled by GCC gcc-4.4.real (Ubuntu 4.4.3-4ubuntu5.1) 4.4.3, 32-bit
(1 row)
Anything I have missed in my upgrade? please help.
Regards
Arthur

AFAIK,
postgres does not have any similar message like that :
* Restarting PostgreSQL 9.2 database server
...done.
This message probably is from your OS upgrade tool, not from postgres.

That is the true version that you have installed.

Check logs of your installation tool, the problems can be different:
Like bug in your installation tool, bug in restarting part of that tool
unable to restart server.

My guess is it installed a parallel version of Postgres for 9.2 and that 8.4.13 is listening to the default port of 5432 which is what you are connecting to. The 9.2 version is probably listening on another port(at a guess 5433). I would do a ps ax to confirm there is more than one instance of Postgres running. > Regards > Arthur > -- Adrian Klaver adrian.klaver@gmail.com

Ubuntu (Debian really) installs the new vesion in parallel and provides the pg_upgradecluster tool to migrate your old data to the new version. Once you are satisfied that everything is working you can use pg_dropcluster to remove the old data and you can then uninstall 8.4. Martin

I've just discovered pg_lsclusters, another Debian tool, which lists all installed Postgres clusters, their ports, data directories, etc - really handy.
