 I have created a simple function to retrieve the IDEDGE give the Point.

 GetEdgeByPoint(topology, geometry::point, tolerance)
 return integer

 tolerance = 0 mean use the Intersection otherwise ST_DWithin().

 It return the integer ID if there is an edge on the Point,
 but if the Point is even a Node it raise an exception.

 If there isn't any edge in the Point, GetEdgeByPoint return 0.

 If near the point there are two or more edges it throw an exception.

 The patch with the code is attach to this ticket.
