Before the Visibility Map, we always vacuumed all pages in a relation when it was vacuumed at all. This means that we froze tuples at vacuum_min_freeze_age, not at autovacuum_max_freeze_age, which is when we do it post-8.4. -- 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
