#1735: ST_MakeValid: exception on geometry
 Reporter:  aperi2007  |       Owner:  strk         
     Type:  defect     |      Status:  assigned     
 Priority:  medium     |   Milestone:  PostGIS 2.0.1
Component:  postgis    |     Version:  trunk        
 Keywords:             |  

Comment(by strk):

 To recap: the issue is with the heuristic used by UnaryUnion generating
 invalid noding.
 I've tested that iterating the noding procedure can eventually handle to
 correctly node.
 Such iteration could be implemented in PostGIS ST_MakeValid to improve
 likelyhood of succeeding.
