The information you want is in pg_user and pg_group. Unfortunately
the list of user ids in a group are stored in an array which makes getting
the login names corresponding to those ids a bit of a pain or if you
are starting with a user finding which groups they are in. In 7.4
the array handling is going to be more powerful (but may still be a contrib)
which might make writing a simple query easy.
