I'm not a fan of SECURITY DEFINER functions for this sort of thing and
don't like the suggestion of simply wrapping functions that provide
superuser-level access in a security definer function and then saying
that giving someone access to that function isn't giving them superuser,
because that's just false.

Thanks!
