# Horizontal Scaling

<Warning>
  **This page is archived.** Fly Postgres (unmanaged) is no longer maintained, and Fly.io Support is not able to provide support or guidance for it. We now offer [Fly.io Managed Postgres](/postgres), our fully-managed database service that handles all aspects of running production PostgreSQL databases.

  These pages are kept for reference and are not listed in the navigation. The full set is indexed on the [Fly Postgres (Unmanaged)](/unmanaged-postgres) page.
</Warning>

Horizontally scale your Postgres cluster with the  [`flyctl machine clone`](/flyctl/cmd/fly_machine_clone) command. Here's an example:

```bash theme={null}
fly machine clone e784079b449483 --region ord --app pg-test
```

You can use [`fly machine status`](/flyctl/cmd/fly_machine_status) to confirm the state of the cluster.
