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 when I 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.

This is correct. 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.

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

read the man pages for pg_upgradecluster and postgresql-common
