<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.
