It isn't in CVS yet, but hopefully before Monday evening you'll be able
to do this:

regression=# create user u1;
CREATE USER
regression=# create user u2;
CREATE USER
regression=# create user u3;
CREATE USER
regression=# create group g1 with user u1,u2;
CREATE GROUP
regression=# create group g2 with user u1,u2,u3;
CREATE GROUP
regression=# \c - u1
You are now connected as new user u1.
regression=> SELECT g.groname FROM pg_group g, pg_user u WHERE u.usename
= current_user AND u.usesysid = ANY (g.grolist);
groname
---------
g1
g2
(2 rows)
