     Type:  defect    |      Status:  new          
 Priority:  critical  |   Milestone:  PostGIS 2.0.0
Component:  topology  |     Version:  trunk        
 Keywords:            |

 I've noticed a drop in edges from input to noded input.
 Most likely due to use of "UNION" vs. "UNION ALL".
 Will add a testcase for it and then fix it.
