Q: what have you got the FSM parameters set to? Q: what exactly is bloating? Without knowing which tables or indexes are growing, it's hard to speculate about the exact causes. Use du and oid2name, or look at pg_class.relpages after a plain VACUUM. It's likely that the real answer is "you need to vacuum more often than every six hours", but I'm trying not to jump to conclusions. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
