Hi,

I have a table with daily partition schema on Postgresql 9.1 where we are keeping 2 years of data.

Often I experience that autovacuum process is busy with old tables where there is no change. How can I stop it?

Please advice.

I typically run a vacuum freeze in old partitions that don't get any changes as part of a maintenance script.  If the tables actually get no changes, autovac should ignore them unless wrap becomes an issue at max_freeze_age... Which, it shouldn't of you vacuum freeze and there are no changes. 

Thanks.
