New description:

 Minor issue but:

 ST_3DDifference returns:


 {{{
 ERROR:  LWGEOM2SFCGAL: Unknown geometry type !
 }}}

 With curved surfaces - a query such as:


 {{{
 SELECT ST_3DDifference('POLYHEDRALSURFACE Z (((-72.2 41.755 0,-72.2 41.755
 1,-72.2 42.755 1,-72.2 42.755 0,-72.2 41.755 0)),((-72.2 41.755 0,-72.2
 42.755 0,-71.2 42.755 0,-71.2 41.755 0,-72.2 41.755 0)),((-72.2 41.755
 0,-71.2 41.755 0,-71.2 41.755 1,-72.2 41.755 1,-72.2 41.755 0)),((-71.2
 42.755 0,-71.2 42.755 1,-71.2 41.755 1,-71.2 41.755 0,-71.2 42.755
 0)),((-72.2 42.755 0,-72.2 42.755 1,-71.2 42.755 1,-71.2 42.755 0,-72.2
 42.755 0)),((-72.2 41.755 1,-71.2 41.755 1,-71.2 42.755 1,-72.2 42.755
 1,-72.2 41.755 1)))'::geometry,'
 MULTISURFACE(CURVEPOLYGON(CIRCULARSTRING(-71.0821 42.3036,-71.4821
 42.3036,-71.7821 42.7036,-71.0821 42.7036,-71.0821 42.3036),(-71.1821
 42.4036,-71.3821 42.6036,-71.3821 42.4036,-71.1821 42.4036)))'::geometry);
 }}}

 Same issue with ST_3DUnion
