In recent versions of Postgres user and group have been folded into
roles. The terms still exist, to roughly mean user=role with login,
group=role without login. There are built in functions to work with
roles and privileges. See:

http://www.postgresql.org/docs/9.2/interactive/functions-info.html

Table 9-51. Access Privilege Inquiry Functions
...
pg_has_role(user, role, privilege)    boolean    does user have privilege for role
pg_has_role(role, privilege)    boolean    does current user have privilege
for role

There are more available.
