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

Oleg
