+### Node Postgres
+
+Use the `node-postgres` driver to connect with Drizzle's [`drizzle-orm/node-postgres`](https://orm.drizzle.team/docs/connect-planetscale-postgres#node-postgres) driver. This is useful for standard PostgreSQL clients, including PlanetScale Postgres.

+```ts [nuxt.config.ts]
+export default defineNuxtConfig({
+  hub: {
+    db: {
+      dialect: 'postgresql',
+      driver: 'node-postgres'
+    }
+  }
+})
+```
+
+Install the required dependencies:
+
+:pm-install{name="drizzle-orm drizzle-kit pg"}
+:pm-install{name="@types/pg" dev}
+
+NuxtHub does not auto-detect `node-postgres`; set `driver: 'node-postgres'` explicitly. When `DATABASE_URL`, `POSTGRES_URL`, or `POSTGRESQL_URL` is set, NuxtHub passes it to Drizzle as the `pg` `connectionString`.
