Given that the hourly purge seems to work well for you, I'd suggest trying it on both tables. Non-FULL vacuum is intended to be run *frequently*, say as often as you've updated or deleted 10% to 50% of the rows in a table. Delaying it until you've had multiple complete turnovers of the table contents will cost you. > As there were too many rows purged for vacuum to > accurately keep track of? Only possible if you don't have the FSM parameters set high enough. Infrequent vacuuming means you need more FSM space, btw. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 6: Have you searched our list archives? http://archives.postgresql.org
