At this point I'm on board with retaining the \dr charter of simply being an easy way to access the detail exposed in pg_roles with some display formatting but without any attempt to convey how the system uses said information. Without changing pg_roles. Our level of effort here, and degree of dependence on superuser, doesn't seem to be bothering people enough to push more radical changes here through and we have good improvements that are being held up in the hope of possible perfection.
