You need v6.4.2-feature-patch which implement LIMIT option:

  LIMIT   This is a new option to the SELECT statement, telling
            the  database  that  only  some  of the rows selected
            should be returned in the result set.

            The added syntax of the LIMIT option is:

                SELECT ... [LIMIT {ALL | lim} [, off]];
            or
                SELECT ... [LIMIT {ALL | lim}] [OFFSET off];

            where lim is a positive integer  value  greater  than
            zero  and off is an integer value greater or equal to
            zero. Both values can be specified as Parameters when
            using the server programming interface (SPI). In this
            case, a zero value given in the argument for the  lim
            parameter means ALL.

 You can find it in patches directory
