I agree that they shouldn't be different, but if this can't be made to
work, perhaps both should fail in this situation? Changing ownership
of objects on a dump/restore seems like a decidedly un-Postgres-like
foot-gun. Granted, this is only applicable in only a small set of
situations, but it's still a foot-gun--a metadata integrity issue if
you will. For what it's worth, I completely agree with Robert's
comments in the thread regarding #5184 [1]. Does the comparison to
template0/1 suggested in that thread merit further consideration?
