36.38. role_udt_grants
  The view
  
   role_udt_grants
  
  is intended to identify
  
   USAGE
  
  privileges granted on user-defined types
   where the grantor or grantee is a currently enabled role.  Further
   information can be found under
  
   udt_privileges
  
  .  The only effective difference
   between this view and
  
   udt_privileges
  
  is that
   this view omits objects that have been made accessible to the
   current user by way of a grant to
  
   PUBLIC
  
  .  Since
   data types do not have real privileges in PostgreSQL, but only an
   implicit grant to
  
   PUBLIC
  
  , this view is empty.
