#3508: ST_ChangeEdgeGeom might be overpicky about collision detection
----------------------+----------------------------
 Reporter:  strk      |      Owner:  strk
     Type:  defect    |     Status:  new
 Priority:  medium    |  Milestone:  PostGIS Future
Component:  topology  |    Version:  2.0.x
 Keywords:            |
----------------------+----------------------------
 The current ST_ChangeEdgeGeom refuses to move an edge when its movement
 would hit an obstacle. While easy to understand, the constraint might be
 overparanoid and could be relaxed to just allow that the topology doesn't
 change (ie: no attributes other than the geometric ones need to change).

 In particular, for dangling edges (right face = left face) a move
 collision does not mean breaking the topology (as no object ends up
 changing face).
