I have little doubt that a deferred insertion buffer of some kind
could help performance on some workloads, though I suspect the buffer
would have to be pretty big to make it worthwhile on a big COPY that
generates mostly-random insertions.  I think the question is not so
much whether it's worth doing but where anyone's going to find the
time to do it.
