If we have the COPY case covered then we have done the only case that has any practical use AFAICS --- you don't use UPDATE or DELETE for bulk loads, and you don't use retail INSERTs either if you are striving for speed. I don't want to see us mucking with the WAL logic without a *whole* lot better rationale than has been presented so far. regards, tom lane
