Rien à voir avec ta question, mais juste pour infos, si tu utilises une
version 8.2 ou supérieure, tu peux remplacer :

INSERT INTO clients.contacts (nom, email, _trigger) VALUES (p_nom,
p_email, p_t);
SELECT id INTO v_id FROM clients.contacts WHERE nom = p_nom AND
email = p_email LIMIT 1;

par

INSERT INTO clients.contacts (nom, email, _trigger) VALUES (p_nom,
p_email, p_t) RETURNING id INTO v_id;
