Comment (by laopsahl):

 Knut a co worker of mee commented that the first line in the example above
 has a spike. Postgis says the line is valid and simple .

 If I remove the spike the code works ok in Postgis Topology.
 {{{
 select CreateTopology('test_snapto');
 select TopoGeo_addLinestring('test_snapto','LINESTRING(609285.46
 6549990.58,609281.0371 6549986.79,609277.63 6549983.87)',0);
 select TopoGeo_addLinestring('test_snapto','LINESTRING(609281.0371
 6549986.79,609292 6549984)',2);
 }}}
