Please clarify. http://www.postgresql.org/docs/8.2/interactive/routine-vacuuming.html#VACUUM-FOR-SPACE-RECOVERY Since VACUUM FULL is not recommended for routine use, it would hardly make sense to use it for autovacuum. If you want to confirm, try selecting from a table while autovacuum is vacuuming it -- since VACUUM FULL locks the table against all other uses, the ability to select proves it's not VACUUM FULL. By the way, I hope you're not considering scheduling regular VACUUM FULL runs against your database. You would wind up regretting that. If you don't believe that, I recommend that you reread the above-cited section until you're convinced. -Kevin
