Instead of talking in circles, let's figure out how to do it. If the issue is only sequence numbers, can we force a column to _only_ get values from the sequence counter, thereby makeing the index span unnecessary? Can't we look up stuff in parent/child index to check for collisions before we add a row? Doesn't seem too hard to me. -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 359-1001 + If your life is a hard drive, | 13 Roberts Road + Christ can be your backup. | Newtown Square, Pennsylvania 19073
