 Our ST_Dump functions are great in that they work for 3D as well asn can
 dup out as triangles/polygons, but we have no easy mechanism to take a set
 of polygons that are triangles, or triangles, or a set of 3D polygons to
 form a polyhedral surface or TIN.  I was going to call this collect, but I
 think Union is more appropriate since it has to consider connectivity
 rules.

 Again didn't check SQL/MM to see if there is such a concept already
