I am not in favor of adding a delay in VACUUM unless people ask for it. Imagine either night vacuum or a vacuum you run in your application after you delete and just before you load a table. Neither want a vacuum. I think people who want a delay will think to ask for it while people who want a quick vacuum will just think that vacuum is slow. -- Bruce Momjian | http://candle.pha.pa.us [EMAIL PROTECTED] | (610) 359-1001 + If your life is a hard drive, | 13 Roberts Road + Christ can be your backup. | Newtown Square, Pennsylvania 19073 ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
