#1789: ST_CreateTopoGeo creates an invalid topology
 Reporter:  strk      |       Owner:  strk         
     Type:  defect    |      Status:  new          
 Priority:  medium    |   Milestone:  PostGIS 2.0.1
Component:  topology  |     Version:  2.0.x        
 Keywords:            |  

Comment(by strk):

 Funny: magnifying the topology (scaling nodes and edges by 1e14) makes
 ValidateTopology happy.
 Trying to "manually" validate the topology I didn't find any obvious

 The validation with original (non scaled) topology was reporting an edge
 crossing a node, but I couldn't confirm _visually_. Looking too much
 visually also hurts (qgis segfaulted...) so will have to recheck in some
 better way.
