Robusness issues in GEOS result in exceptions thrown at ST_ChangeEdgeGeom time, where verifying that the incurred change would not change the data topology.
There could be improvements in that computation. For example we could skip the check completely if no nodes other than the endpoints of the line would fall within the extent of either old or new edge…
