Comment (by laopsahl):

 Why is this code working ok ?

 {{{
 select DropTopology('test_snapto');
 select CreateTopology('test_snapto');
 select TopoGeo_addLinestring('test_snapto','LINESTRING(609285.46
 6549990.58,609277.63 6549983.87)',0);
 SELECT ST_Length(geom) from test_snapto.edge_data;
 select TopoGeo_addLinestring('test_snapto','LINESTRING(609281.0371
 6549986.79,609292 6549984)',2);

 }}}

 And not this, where i add a new linstrings and then removes it, before
 adding the last line string ?

 {{{

 select DropTopology('test_snapto');
 select CreateTopology('test_snapto');
 select TopoGeo_addLinestring('test_snapto','LINESTRING(609285.46
 6549990.58,609277.63 6549983.87)',0);
 select TopoGeo_addLinestring('test_snapto','LINESTRING(609277.63
 6549983.87,609281.0371 6549986.79)',0);
 SELECT ST_Length(geom) from test_snapto.edge_data;
 select ST_RemEdgeModFace('test_snapto', 2);
 SELECT ST_Length(geom) from test_snapto.edge_data;
 select TopoGeo_addLinestring('test_snapto','LINESTRING(609281.0371
 6549986.79,609292 6549984)',2);

 }}}
