I don't understand why you would expect overwriting to win here. What types of updates do you do on these tables? Normally I found using update on such a table was too awkward to contemplate so I just delete all the relation records that I'm replacing for the key I'm working with and insert new ones. This always works out to be cleaner code. In fact I usually leave such tables with no UPDATE grants on them. In that situation I would have actually expected Postgres to do as well as or better than Oracle since that makes them both functionally equivalent. -- greg ---------------------------(end of broadcast)--------------------------- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
