 <sect1 id="infoschema-role-udt-grants">
  <title><literal>role_udt_grants</literal></title>

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