Edit geometries

The following functions are available to edit 3D geometries:

Function	Description
ST_AddZ	Add a value to the z-coordinate of a Geometry
ST_Interpolate3DLine	Return a Geometry with a interpolation of z values.
ST_MultiplyZ	Return a Geometry’s z-values by a factor
ST_Reverse3DLine	Reverse a Geometry thanks to the z-values of its first & last coordinates
ST_UpdateZ	Update the z-values of a Geometry
ST_ZUpdateLineExtremities	Update the start and end z-values of a Geometry
