here are the constraints of the abilitazione table
ALTER TABLE public.abilitazione
ADD CONSTRAINT abilitazione_pkey PRIMARY KEY(comuneid, cassonettoid,
chiaveid);
ALTER TABLE public.abilitazione
ADD CONSTRAINT abilitazione_cassonettoid_fkey FOREIGN KEY (comuneid,
cassonettoid) REFERENCES public.cassonetto (comuneid, cassonettoid) ON
UPDATE RESTRICT ON DELETE RESTRICT;
ALTER TABLE public.abilitazione
ADD CONSTRAINT abilitazione_chiaveid_fkey FOREIGN KEY (comuneid,
chiaveid) REFERENCES public.chiave (comuneid, chiaveid) ON UPDATE
RESTRICT ON DELETE RESTRICT;
here those of cassonetto and chiave:
ALTER TABLE public.cassonetto
ADD CONSTRAINT cassonetto_pkey PRIMARY KEY(comuneid, cassonettoid);
ALTER TABLE public.chiave
ADD CONSTRAINT chiave_pkey PRIMARY KEY(comuneid, chiaveid);
I get the SQL from pgAdmin3 (great piece of sofware!;-)

Excuse me for the missing SQL, but i had tried to keep the message as
simple as possible.
The unique difference form when the exception was raised and now (that
it isn't) is the rule added:
CREATE OR REPLACE RULE abilita_ins_rl AS ON INSERT TO abilitazione
WHERE (EXISTS (
SELECT 1 FROM abilitazione
WHERE (((abilitazione.comuneid = new.comuneid )
AND (abilitazione.cassonettoid = new.cassonettoid ))
AND (abilitazione.chiaveid = new.chiaveid ))))ù
DO INSTEAD UPDATE abilitazione SET abilitata = new.abilitata
WHERE (((abilitazione.comuneid = new.comuneid )
AND (abilitazione.cassonettoid = new.cassonettoid ))
AND (abilitazione.chiaveid = new.chiaveid ));
I hope now is more clear.
The version is that come with debian unstable (7.3.4 if I remember
correctly)
Thank you for the immediate responses
ciao, Michele
