   The view <literal>column_privileges</literal> identifies all
   privileges granted on columns to a currently enabled role or by a
   currently enabled role.  There is one row for each combination of
   column, grantor, and grantee.

  <para>
   If a privilege has been granted on an entire table, it will show up in
   this view as a grant for each column, but only for the
   privilege types where column granularity is possible:
   <literal>SELECT</literal>, <literal>INSERT</literal>,
   <literal>UPDATE</literal>, <literal>REFERENCES</literal>.
