Comment (by strk):

 This query confirms edge 3 is found closer than edge 4:

 {{{
 =# select edge_id, st_distance(geom, 'POINT(18.006691126034692
 69.04048768506776)') from t5782.edge order by geom <->
 'POINT(18.006691126034692 69.04048768506776)' limit 3;
  edge_id |      st_distance
 ---------+-----------------------
        3 | 9.716835623092273e-05
        4 | 9.716835623285099e-05
        2 | 9.740220330897892e-05
 (3 rows)
 }}}

 We don't even get an equidistance. On the other hand order by angle around
 nodes confirms edge 4 is on the left of edge 3. Puzzling.
