Comment (by bwibo):

 I believe that there are use cases for both constrained and non-
 constrained delaunay triangulation. So maybe two different functions or a
 switch to control the behavior of the triangulation would be best for most
 people.

 I am not an expert on PostGIS/SFCGAL architecture, but if possible, I
 would rather add another function or offer ST_DElaunayTriangles with
 another signature, e.g. ST_DelauneyTriangles(geometry,
 boolean=enableConstrainedTriangluation), if SFCGAL backend is available.
