The view role_usage_grants is meant to identify
USAGE privileges granted on various kinds of
objects to a group that the current user is a member of. In
PostgreSQL, this currently only applies
to domains, and since domains do not have real privileges in
PostgreSQL, this view is empty. Further
information can be found under usage_privileges.
In the future, this view may contain more useful information.
