Re: pg_clog questions

I have autovacuum turned on with the default settings.
The issue is that we are mostly inserting records, sometimes updating,
very seldom deleting.  The ones which get deleted are in partitioned
tables, and will be done away with via truncate once the data retention
period is over.

Logs show that autovacuum is running on all databases.

VACUUM.  If they're not disappearing, you aren't running an adequate
vacuum regime --- missing out some databases, perhaps?
