Comment (by Lars Aksel Opsahl):

 Replying to [comment:12 strk]:
 > It's interesting to note that calling TopoGeo_addPoint with that close-
 by vertex does already implement the edge-snapping and merge:

 t6034.edge_data where edge_id = 2 ) );

 added edges and create a node there if they are within tolerance from
 edges NOT having them as vertices.

 I like this solution because this should mostly affect corner cases like
 this one.
