ST_Points

Description

Returns a MultiPoint containing all of the coordinates of a geometry. Does not remove points that are duplicated in the input geometry, including start and end points of ring geometries. (If this behavior is undesired, duplicates may be removed using ST_RemoveRepeatedPoints ).

M and Z ordinates will be preserved if present.

This method supports Circular Strings and Curves

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

Availability: 2.3.0
