#941: ST_ModEdgeHeal : wrong response on non-existent edge
 Reporter:  aperi2007  |       Owner:  strk         
     Type:  defect     |      Status:  new          
 Priority:  medium     |   Milestone:  PostGIS 2.0.0
Component:  topology   |     Version:  trunk        
 Keywords:             |  
 try-ing this
 select topology.ST_ModEdgeHeal('topo_test',10000, 2);

 where 10.000 is a non-existent edge.
 I have this response:

  ERROR: TopoGeom 28 in layer 1 (topo_test.linee_topo.topo_geom) cannot be
 represented healing edges 10000 and 2

 I guess according to ISO the response should be
 "SQL/MM Spatial exception – non-existent edge"

 Same result for the third argument:
 select topology.ST_ModEdgeHeal('topo_test',1, 10000);
