 Priority:  medium       |   Milestone:  PostGIS 2.0.0
Component:  topology     |     Version:  trunk

-------------------------+--------------------------------------------------
 Based on standard description for ST_AddIsoEdge you can't use the function
 to create a non-isolated edge, which is an edge whose endnodes are shared
 with another edge.

 Rather than computing this sharing, the function could use the node's
 "containing_face" field to tell if it was isolated or not.
 Doing so would speed up operations and catch malformed topologies earlier
 rather than tolerating them.
