ALTER SYSTEM is already heavily restricted.  I don't think we need random
kluges added to the permissions system.  I especially don't believe in
kluges to the effect of "superuser doesn't have all permissions anymore".

If you nonetheless feel that that's a good idea for your use case,
you can implement the restriction with an event trigger or the like.
