Comment(by colivier):

 For the record:

 Functions available now both with GEOS and SFCGAL
  - ST_Intersects
  - ST_3DIntersects
  - ST_Intersection
  - ST_Area
  - ST_Distance
  - ST_3DDistance

 2D functions should behave quite the same,
 3D functions should be improved (handling more geometry type)


 New functions available only when SFCGAL support activated

 - postgis_sfcgal_version()
 - ST_3DIntersection(geom1 geometry, geom2 geometry)
 - ST_Tesselate(geometry)
 - ST_3DArea(geometry)
 - ST_Extrude(geometry, float8, float8, float8)
 - ST_ForceLHR(geometry)
 - ST_Orientation(geometry)
 - ST_Minkowski(geometry, geometry)
 - ST_StraightSkeleton(geometry)



 New function related to SFCGAL stuff,
 but in PostGIS land:

  - ST_force_sfs(geometry)
