The view usage_privileges is meant to identify
USAGE privileges granted on various kinds of
objects to the current user or by the current user. In
PostgreSQL, this currently only applies
to domains, and since domains do not have real privileges in
PostgreSQL, this view shows implicit
USAGE privileges granted to
PUBLIC for all domains. In the future, this
view may contain more useful information.
