 ## Required Environment Variables
 
-- `PGHOST` — Postgres host. On Railway, use the internal hostname (e.g. `postgres.railway.internal`). The Docker Compose default `database_postgres` does not resolve on Railway.
-- `PGPASSWORD` — Postgres password.
+- `PLANEXE_POSTGRES_HOST` — Postgres host. On Railway, use the internal hostname (e.g. `postgres.railway.internal`). The Docker Compose default `database_postgres` does not resolve on Railway.
+- `PLANEXE_POSTGRES_PASSWORD` — Postgres password.
