+-- Script de création définitive pour serveur de production
+

+    END IF;
+    
+    RAISE NOTICE 'Toutes les tables dépendantes sont présentes.';
+END $$;
+
+-- 2. Supprimer la table si elle existe (ATTENTION: supprime les données)
+DROP TABLE IF EXISTS avoirs CASCADE;
+
+-- 3. Créer la table avec la structure exacte
+CREATE TABLE avoirs (
+    id SERIAL PRIMARY KEY,
+    supplier_id INTEGER NOT NULL,
+    group_id INTEGER NOT NULL,
+    invoice_reference VARCHAR(255),
+    amount DECIMAL(10,2),

+ALTER TABLE avoirs 
+ADD CONSTRAINT chk_avoirs_status

+
+-- 6. Créer les index pour les performances
+CREATE INDEX idx_avoirs_supplier_id ON avoirs(supplier_id);

+CREATE INDEX idx_avoirs_created_by ON avoirs(created_by);
+CREATE INDEX idx_avoirs_status ON avoirs(status);

+    RETURN NEW;
+END;

+-- 8. Test final avec une insertion
+INSERT INTO avoirs (

+WHERE EXISTS (SELECT 1 FROM suppliers) 
+  AND EXISTS (SELECT 1 FROM groups) 
+  AND EXISTS (SELECT 1 FROM users);
+
+-- 9. Vérifier la création
+SELECT 
+    'SUCCESS: Table avoirs créée avec ' || COUNT(*) || ' enregistrement(s)' as result

+-- 10. Nettoyer le test
