Bug Description

ST_UNION does not perform duplicate weedout. The union of 2 identical POINTs is returned as a MULTIPOINT containing 2 identical POINTS. Postgis returns a single POINT.

 SELECT AsText( ST_UNION( GeometryFromText(' POINT( 4 4 ) ') , GeometryFromText(' POINT( 4 4 ) ') ) );

returns:

MULTIPOINT(4 4,4 4)
