!     <literal>FOR UPDATE</literal> may appear before
!     <literal>LIMIT</literal> for compatibility with
!     <productname>PostgreSQL</productname> versions before 7.3.  It
!     effectively executes after <literal>LIMIT</literal>, however, and
!     so that is the recommended place to write it.

     <para>
!     It is possible for a <command>SELECT</> command using both 
!     <literal>LIMIT</literal> and  <literal>FOR UPDATE</literal> 
!     clauses to return fewer rows than specified by <literal>LIMIT</literal>.
!     This is because <literal>LIMIT</> selects a number of rows,
!     but might then block requesting a <literal>FOR UPDATE</literal> lock.
!     Once the <literal>SELECT</> unblocks, the query qualifiation might not
!     be met and the row not be returned by <literal>SELECT</>.
