Tom, > Are you sure you're not thinking of stats for functional indexes?
Positive. I even remember seeing that the patch was accepted. The patch specifically had to do with a multi-column correlation algorithm for improving the selectivity of multi-column indexes. Problem is, with 1400 posts per month August to October, I can't find it, and the keywords that I think are obvious don't turn anything up. -- -Josh Berkus Aglio Database Solutions San Francisco ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
