Horizontal Scaling

This document applies to Postgres clusters running on our next-gen Apps V2 architecture (Fly Machines). If you created your cluster using any flyctl version before v0.0.412, refer to Fly Postgres on Apps V1 and Multi-region PostgreSQL instead.

Horizontally scale your Postgres cluster with the flyctl machine clone command. Here's an example:

fly machine clone e784079b449483 --region ord --app pg-test

You can use fly machine status to confirm the state of the cluster.
