The interpretation can go both ways I guess. Now I find the argument
to treat a HBA entry based on privileges and not membership quite
appealing in terms of consistency wiht SET ROLE, particularly
considering the recent thread with predefined roles. Also, it seems
to me here that it would become easier to reason around role
hierarchies, one case being HBA entries that include predefined
roles for the role(s) to match.
