I don't think there's much point in getting excited about the order in
which things exit. If we're agreed (and we seem to be, modulo Tom)
that the backends should exit quickly if the postmaster dies, then
worrying about whether the utility processes exit slightly before or
slightly after that doesn't excite me very much.
