Map ::wkb_blob as an alias to ST_ASWKB?

[marklit]

It seems this functionality is there already if called in the right way.

D SELECT ST_POINT(52.347113, 4.869454)::wkb_blob AS test;
Error: Conversion Error: Unimplemented type for cast (GEOMETRY -> WKB_BLOB)

D SELECT ST_ASWKB(ST_POINT(52.347113, 4.869454)) test;
