I don't see the problem, since the default execution mode for functions is
SECURITY INVOKER.
But you can easily change that:
ALTER DEFAULT PRIVILEGES FOR ROLE function_creator REVOKE EXECUTE ON FUNCTION FROM PUBLIC;
You named function_creator here when in this example the role creating the new object is postgres. How is it that the default privilege granted to public doesn’t seem to care who the object creator is yet when revoking the grant one supposedly can only do so within the scope of a single role?
