# Horizontal Scaling

<Warning>
  Important: We are not able to provide support or guidance for unmanaged Postgres. We now offer [Fly.io Managed Postgres](/mpg) , our fully-managed database service that handles all aspects of running production PostgreSQL databases.
</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.
