Comment:

 It seems to quite hard to create a small failing context.

 I have now tried with this cmd's to geom involved and even then I am not
 able to cases that does produces a failing tests for all cases.


 {{{
 Format('SELECT distinct geom, edge_id FROM %1$s.edge_data WHERE
 abs(next_left_edge) = %2$s or edge_id = %2$s or abs(next_right_edge) =
 %2$s order by abs(edge_id);',
                         _topology_name, error_edge_id);

 Format('SELECT distinct geom, edge_id FROM %1$s.edge_data WHERE
 ST_intersects(%2$L,geom);',_topology_name,new_line);

 }}}


 This basicly means in some case we need the whole topology to create an
 error context.
