It's not so much an issue of when the last auto-analyze was as an issue of the number of rows in write transactions against that table in the last X minutes. This is where it really hurts us that pg_stat_user_tables is not time-based. -- Josh Berkus PostgreSQL Experts Inc. http://pgexperts.com -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
