Comment (by strk):

 The query I'm using against the whole "ucs_rt" table, which can be found
 here:
 http://www502.regione.toscana.it/geoscopio/topologia_uso_suolo.7z

 Is as follows:

 {{{
 DO $$
 declare
   rec record;
 begin
   for rec in select gid, (ST_Dump(ST_Boundary(geom))).* from ucs_rt
       order by st_length(geom)
       offset 65000 limit 11000
   loop
     begin
       perform topology.TopoGeo_addLinestring('ucs_rt_topo', rec.geom);
     exception when others then
       RAISE WARNING 'Error adding boundary line % of record with gid %:
 %',
         rec.path, rec.gid, SQLERRM;
       insert into ucs_rt_topo.problematic values ( rec.geom );
     end;
   end loop;
 end;
 $$ language 'plpgsql';
 }}}
