True. I implemented the SAVEPOINTs solution across the board. We'll see what kind of difference it makes. If it's fast enough, I may be able to do without that.

I was thinking about that (as per your presentation last week) but my problem is that when I'm building up a series of inserts, if one of them fails (very likely in this case due to a unique_violation) I have to rollback the entire commit. I asked about this in the novice forum and was advised to use SAVEPOINTs. That seems a little clunky to me but may be the best way. Would it be realistic to expect this to increase performance by ten-fold?
if you insert into a different table before doing a bulk insert later, you can de-dupe before doing the insertion, eliminating the issue entirely.
