I suggest you turn log_min_messages more verbose, to DEBUG2, and see if there are any entries in there regarding autovacuum. If it's running, you would see it. You would get a message after autovacuum_naptime seconds. How long is autovacuum_naptime anyway? -- Alvaro Herrera http://www.CommandPrompt.com/ PostgreSQL Replication, Consulting, Custom Development, 24x7 support
