Hm. Evidently when Peter rewrote pg_dumpall in C, he was a little too
narrow-minded about which pg_dump options should be accepted by
pg_dumpall. (The old script version would pass through almost anything.)
I wonder if anything else besides -s ought to be added back.
But as to the matter at hand: the fact that no one has tested pg_upgrade
since then should give you a good clue as to (a) its usefulness and (b)
how much you should trust it. The reason it's in contrib and not in the
main distro is that it's unreliable.
