If you need it there's nothing wrong with running vacuum even more often than this. As often as every 5 minutes isn't unheard of. You should also look at raising the fsm settings. You need to run vacuum often enough that on average not more tuples are updated in the intervening time than can be kept track of in the fsm settings. So raising the fsm settings allow you to run vacuum less often without having things bloat. There's a way to use the output vacuum verbose gives you to find out what fsm settings you need. But I don't remember which number you should be looking at there offhand. -- greg ---------------------------(end of broadcast)--------------------------- TIP 6: Have you searched our list archives? http://archives.postgresql.org
