-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Il 05/12/2013 17:16, Andy Colson ha scritto: Setting vacuum_freeze_table_age to 0 forces VACUUM to always scan all pages, effectively ignoring the visibility map. In this way a scan of the whole table is done, ensuring all old XIDs are replaced by FrozenXID. vacuum_freeze_table_age is a parameter with context 'user', meaning that you can set it during a session and run a "vacuum freeze" with the modified setting.
