Name

ST_Reverse — Return the geometry with vertex order reversed.

Synopsis

geometry ST_Reverse(geometry g1);

Description

Can be used on any geometry and reverses the order of the vertexes.

Enhanced: 2.4.0 support for curves was introduced.

This function supports 3d and will not drop the z-index.

This function supports Polyhedral surfaces.

Examples

SELECT ST_AsText(the_geom) as line, ST_AsText(ST_Reverse(the_geom)) As reverseline
FROM
(SELECT ST_MakeLine(ST_Point(1,2),
		ST_Point(1,10)) As the_geom) as foo;
--result
		line         |     reverseline
