Comment (by laopsahl):

 Here is the list of all index I added when running resolve overlap

 {{{
   EXECUTE Format('CREATE INDEX ON %s.relation(layer_id)',
 (_topology_info).topology_name);
   EXECUTE Format('CREATE INDEX ON %s.relation(abs(element_id))',
 (_topology_info).topology_name);
   EXECUTE Format('CREATE INDEX ON %s.relation(element_id)',
 (_topology_info).topology_name);
   EXECUTE Format('CREATE INDEX ON %s.relation(topogeo_id)',
 (_topology_info).topology_name);
