Yes, you're correct. If it's set at 100 it should still work by using the OS buffer cache to catch up (and then be within a few buffers), but I think you're right that 16 is the correct value. I'll change my patch to be 16. I don't think I need to send along a diff ;) Thanks, Jeff Davis ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
