Comment (by strk):

 The updated test (with correct syntax):
 {{{
 SELECT CreateTopology('topotest');
 SELECT ST_AddIsoNode('topotest', 0, ST_MakePoint(-180, 0));
 SELECT ST_AddIsoNode('topotest', 0, ST_MakePoint(0, 0));
 SELECT ST_AddIsoEdge('topotest', 1, 2, 'LINESTRING(-180 0, 0
 0)'::geometry);
 SELECT 'before', * FROM ValidateTopology('topotest');
 SELECT ST_ModEdgeSplit('topotest', 1, ST_MakePoint(-20, 0));
 SELECT 'after', * FROM ValidateTopology('topotest');
 }}}
