I have gps coordinates as point outside the linestring/road. I have interpolated to the closest point in the line using ST_Line_Interpolate_Point(). Now I need to draw line through these points and it must be through the road topology. But ST_MakeLine() simply draws lines through these points i.e it doesnot check the road topology/linestring.
