(1) Whether a view can access a table is determined by the ownership of
the view, not of the user using the view.
(2) It might be nice if the view's permissions were inherited by functions
called by the view, but we've not made that happen. You might be able to
approximate it by marking such functions SECURITY DEFINER; although that
makes the function's permissions those of the function's owner not the
view's owner.
