I think the entire idea is a waste of time anyway. 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.
