Btw., it would be really nice if some limited form of this could get done,
so I could finish the information schema views pertaining to group
privileges. I'd just need a way to find out what users are in what
groups. If unnest() would work for locally constant arguments, I think it
could be done like

SELECT g.groname
FROM pg_user u, pg_group g
WHERE u.usesysid IN (SELECT * FROM UNNEST((SELECT grolist FROM pg_group WHERE grosysid = g.grosysid)))
AND u.usename = current_user;

Or is there some other way to do this now?
