Hi Steve,
Thanks for your reply.
My Postgresql version is 8.2. I amn't sure we have the autovacuum job running or not? How can I check it ?

Unless something is broken it is already running. You can connect to the db and run "show autovacuum;". It should be on.

Alternately, run "show all;" and scroll down to look at all the autovacuum settings.

You can also check the running processes. On *nix: if you run "ps -ef | grep postgres" (assuming typical setups where PostgreSQL is running as the postgres user) you will see something like: postgres 14698 1 0 Jan10 ? 01:20:57 /usr/bin/postgres -p 5432 -D /var/lib/pgsql/data
postgres 14700 14698 0 Jan10 ? 00:07:20 postgres: writer process
postgres 14701 14698 0 Jan10 ? 00:03:09 postgres: wal writer process
postgres 14702 14698 0 Jan10 ? 00:00:21 postgres: autovacuum launcher process
postgres 14703 14698 0 Jan10 ? 00:51:48 postgres: stats collector process
...

The "autovacuum launcher process" is the one that handles automatically running vacuum when it is appropriate.

Cheers,
Steve
