#2086: EdgeMerge(signed_edge_id)
 Reporter:  strk         |       Owner:  pramsey      
     Type:  enhancement  |      Status:  new          
 Priority:  medium       |   Milestone:  PostGIS 2.1.0
Component:  postgis      |     Version:  2.0.x        
 Keywords:               |  

Comment(by strk):

 The implementation could be similar to that of GetEdgeRing, which is
 walking around a link and sewing until a node of degree != 2 is found.
 A signed edge id would give the direction to follow. Positive to walk
 forward, negative to walk backward.
