+## Corrigir senha do Postgres
+
+Se o backend mostrar `FATAL: password authentication failed for user "leadscraper"`, o `.env` e o volume do Postgres ficaram com senhas diferentes. Realinhe a senha do usuario no banco usando o valor atual do `.env`:
+
+```bash
+cd /opt/Prospeccao_SeConectai
+cat .env | grep DB_PASSWORD
+docker compose -f docker-compose.prod.yml exec postgres psql -U postgres -d leadscraper
+```
+
+Dentro do `psql`, execute trocando `<senha_do_env>` pelo valor de `DB_PASSWORD`:
+
+```sql
+ALTER USER leadscraper WITH PASSWORD '<senha_do_env>';
+\q
+```
+
+Depois reinicie os servicos:
+
+```bash
+docker compose -f docker-compose.prod.yml restart backend caddy
