#5093 new enhancement

ST_Simplify(TopoGeometry) returns NULL on collapse

The ST_Simplify(TopoGeometry) function makes no effort to preserve topology, and may result in returning a NULL value for collapsed elements (like closed linearring). It may be nice to enhance it, using the topological information.

An example implementation could enforce 2 additional nodes on single-node linestrings.
