FWIW, I never objected to the idea of being able to disable ALTER
SYSTEM. I felt that it ought to be part of a larger feature that
would provide a more bulletproof guarantee that a superuser can't
alter the system configuration; but I'm clearly in the minority
on that. I'm content with just having it disable ALTER SYSTEM
and no more, as long as the documentation is sufficiently clear
that an uncooperative superuser can easily bypass this if you don't
back it up with filesystem-level controls.
