ST_Reverse — Return the geometry with vertex order reversed.
geometry ST_Reverse(
geometry g1)
;
Can be used on any geometry and reverses the order of the vertices.
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.
