     Type:  enhancement  |      Status:  new          
 Priority:  medium       |   Milestone:  PostGIS 2.0.0
Component:  topology     |     Version:  trunk        
 Keywords:               |  
-------------------------+--------------------------------------------------
 I belive the current topology.AddFace could be pretty much faster than it
 is, especially for big polygons, composed by many edges, if the code used
 prepared geometries implementation rather than computing full intersection
 matrix for each candidate edge.

 Early tests show improvements of up to 45%.
