Description

Constructs a PostGIS ST_Geometry object from the OGC Extended Well-Known binary (EWKT) representation.

	The EWKB format is not an OGC standard, but a PostGIS specific format that includes the spatial reference system (SRID) identifier

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

This method supports Circular Strings and Curves

Examples

line string binary rep 0f LINESTRING(-71.160281 42.258729,-71.160837 42.259113,-71.161144 42.25932) in NAD 83 long lat (4269).

	NOTE: Even though byte arrays are delimited with \ and may have ', we need to escape both out with \ and ''. So it does not look exactly like its AsEWKB representation.
