I noitce that adding a new node over a vertex of a pre-existent edge seem
don't split it.
select
topology.AddEdge('schema_topo',ST_GeomFromEWKT('SRID=3003;LINESTRING(4 4,
5 5, 6 6)'));
select topology.AddNode('schema_topo',ST_GeomFromEWKT('SRID=3003;POINT(5
5)'));
I think
starting from
EDGE(4 4,5 5,6 6)
and adding a node in 5 5 it could split the edge in
edge(4 4, 5 5) + edge (5 5, 6 6)
