  <para>
   The view <literal>role_column_grants</literal> identifies all
   privileges granted on columns where the grantor or grantee is a
   currently enabled role.  Further information can be found under
   <literal>column_privileges</literal>.  The only effective
   difference between this view
   and <literal>column_privileges</literal> is that this view omits
   columns that have been made accessible to the current user by way
   of a grant to <literal>PUBLIC</literal>.
