What I would actually like to see happen is that pg_upgrade uses a
standalone backend, with no postmaster running at all for the entire
procedure. Having a live postmaster connected to the system just
opens the door to getting screwed up by some other user connecting to
the database. But that's a bigger change than I dare try to make right
now...
