New issue 103 by robe.... at cityofboston.gov: Box3D always gets cast to 2D  
geometry
http://code.google.com/p/postgis/issues/detail?id=103

Actually not sure if this is solvable.  But ST_SetSRID, ST_Force_3DZ all
lose the Z coordinate value of a BOX3D.

Example:

SELECT ST_AsEWKT(ST_Force_3DZ(ST_Extent3D(foo.the_geom))) As b3extentpoly,
ST_Extent3D(foo.the_geom) As b3extent
FROM (SELECT ST_MakePoint(x,y,z) As the_geom
	FROM generate_series(1,3) As x
		CROSS JOIN generate_series(1,2) As y
		CROSS JOIN generate_series(0,2) As Z) As foo;

Yields:
b3extentpoly                                 b3extent
POLYGON((1 1 0,1 2 0,3 2 0,3 1 0,1 1 0)) ;BOX3D(1 1 0,3 2 2)

I would expect the POLYGON value to have some 2 z coords in there.
