#788: Topology: ST_NewEdgesSplit don't work with more edges connected
------------------------+---------------------------------------------------
Reporter: aperi2007 | Owner: strk

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

Comment(by robe):
Strk,
doesn't ST_NewEdgesSplit always delete the original edge and create 2 new
ones. (We would use ST_ModEdgeSplit (for the other behavior).
In which case shouldn't passing edge number 1 in again return a non-
existent edge error.
That was my understanding scanning the code you have and also
corroborating with the SQL-MM doc I mentioned earlier. Or do we just have
a dangling record somewhere.
Can you verify I documented this right?
