Overview
Constructs a WKB Polygon value from a number of WKB LineString arguments. If any argument does not represent the WKB of a LinearRing (that is, not a closed and simple LineString) the return value is NULL.
EXAMPLES
CREATE TABLE polygon (c1 POLYGON);
INSERT INTO polygon VALUES
(Polygon(LineString(Point(0,0), Point(1,1), Point(2,2), Point(0,0)),
LineString(Point(1,2), Point(2,3), Point(3,4), Point(1,2))));
SELECT ST_AsText(c1) FROM polygon;
