I'm a bit PostGIS oriented. There's no support for EMPTY whatever
in PostGIS except GEOMETRYCOLLECTION. As always I'd follow
JTS, so if the plan is to support any kind of empty geom
we should drop the ::createEmptyGeometry() and ensure no
memory violation is triggered by EMPTY types *and* results
are semantically correct.
