The view usage_privileges is meant to identify
USAGE privileges granted on various kinds of
objects to a currently enabled role or by a currently enabled role.
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.
