If you put all the variants in the same file, diff is *still* not going
to work very well. At least not unless you solve the problems that keep
pg_dump from dumping objects in a consistent order ... and once you do
that, you don't need this patch.

Yeah, that's exactly it. I can think of some possible uses for
splitting up pg_dump output, but frankly "to ease diff-ing" is not
one of them. For that problem, it's nothing but a crude kluge that
only sort-of helps. If we're to get anywhere on this, we need a
better-defined problem statement that everyone can agree is worth
solving and is well solved with this particular approach.
