Subject: [PATCH] =?UTF-8?q?Fix:=20Conversion=20SQL=20SQLite=20=E2=86=92=20?=
 =?UTF-8?q?PostgreSQL?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Correction de TOUTES les requêtes SQL pour PostgreSQL:

1. Paramètres: ? → $1, $2, $3...
   - 234 conversions automatiques
   - auth.routes.js: WHERE username = $1
   - Tous les routes et services corrigés

2. Booléens: 0/1 → TRUE/FALSE
   - WHERE enabled = 1 → WHERE enabled = TRUE
   - WHERE completed = 0 → WHERE completed = FALSE
   - rss-scheduler.js ligne 154: corrigé

ERREURS RÉSOLUES:
- ✅ "syntax error at end of input" (auth login)
- ✅ "operator does not exist: boolean = integer" (RSS)

Script: scripts/convert-sql-to-postgres.js
- Conversion automatique intelligente
- Gère WHERE, INSERT, UPDATE, DELETE, SELECT
- Remplace ? par $N selon ordre
- Convertit booléens 0/1 → TRUE/FALSE

Fichiers modifiés:
- routes/*.js (9 fichiers)
- services/*.js (2 fichiers)
- 234 requêtes SQL corrigées

La connexion et les flux RSS devraient maintenant fonctionner.
