I recently applied the attached patch to prevent recreation of the
current database user in the dump file when in binary upgrade mode.
This was necessary because pg_upgrade will fail on any error from a
pg_dumpall restore.
It would be nice of we could do the same for non-binary-upgrade
pg_dumpall dumps, but I assume we can't because the restore might be
performed by a super user who is different from the dump user, right?
