#2087: Speedup GetRingEdges
 Reporter:  strk         |       Owner:  strk         
     Type:  enhancement  |      Status:  new          
 Priority:  medium       |   Milestone:  PostGIS 2.0.2
Component:  topology     |     Version:  2.0.x        
 Keywords:               |  
 I belive GetRingEdges could be speed up by at least
 a factor of 10 by using a recursive CTE.
 Recursive CTE are supported since 8.4 so this could be put in 2.0
