--------------------+---------------------------
 Reporter:  robe    |      Owner:  robe
     Type:  defect  |     Status:  assigned
 Priority:  low     |  Milestone:  PostGIS 3.1.5

 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
