There's also ALTER ROLE and ALTER DATABASE, which provide more ways to
set GUCs. I agree that we could choose make distinctions here, but I
think if we make too many distinctions, it will become complicated to
administer. And if we don't have *any* way to delegate ALTER SYSTEM,
then I think we have missed the mark.
