Doesn't mean we shouldn't strive to improve it. The present code for estimating number of groups is new in 7.4 and I'm sure there are things that need to be done to it. I'd like to think that factor-of-1000 errors on simple cases are not the best we can do. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
