Also, I attach a new description of the UPSERT feature. For me, UPSERT
was always about guarantees that make statements work robustly under
standard operating conditions -- a novice user should be able to write
a simple UPSERT statement and forget about it. It's really hard to
explain how that can be guaranteed, but the basic guarantee itself is
simple, and matters a lot.
I think that the proposed wording conveys that. I also think that it's
important that this message is prominently conveyed, because these
issues cause no end of confusion.
