  The view
  
   role_usage_grants
  
  identifies
  
   USAGE
  
  privileges granted on various kinds of
   objects where the grantor or grantee is a currently enabled role.
   Further information can be found under
  
   usage_privileges
  
  .  The only effective difference
   between this view and

  is that
   this view omits objects that have been made accessible to the
   current user by way of a grant to
  
   PUBLIC
  
  .
