Description: ERROR: failed to build any 7-way joins

After migrating to 8.2 I received an error:
ERROR: failed to build any 7-way joins
SQL state: XX000
STATEMENT: select * from v_well_main w LEFT OUTER JOIN v_state_main s ON
(w."Id_well"=s."Id_wl") LEFT OUTER JOIN v_expl_main e ON
(w."Id_well"=e."Id_wl") where w."Id_dep"=7
View v_well_main contained statement:
SELECT w."Id_well", w."Name_wl", w."Num", w."Cod", c."Name" AS

LEFT JOIN "Org_dic" o ON w."Passp_org" = o."Id_org"
WHERE v."Id_well" = w."Id_well" AND c."Id_cat" = w."Categor"
ORDER BY w."Num";
The query was executed in pgAdmin III
If STATEMENT change to:
select * from v_well_main w where w."Id_dep"=113
then it executed OK
