Start A* star search from nearest edge

Description

The better way for shortest path A* search would be starting with the closest edge, not with the closest node. This is already the case with Shooting* shortest path.

It would be nice to be able to start (and end) the shortest path linestring not with a complete edge but with the relevant section of the edge.

Then it would be possible to use 

ST_line_locate_point(LineString, Point)

to locate the closest point on the closest edge, and draw the relevant substring only 

ST_line_substring(linestring, start, end)
