You can resize your instance by changing to a different configuration of server family, server size and storage size. Resizing view After selecting the desired configuration, click the "Update" button to start the resizing process. The resizing process may take some time to complete, depending on the size of your database and the resources allocated to your instance. Once the process is complete, your instance will failover to the desired configuration. This involves a brief interruption during which the database will be unavailable. If a [maintenance window](/managed-postgresql/configuration-and-settings#maintenance-windows) is configured, the failover will be scheduled for the next available maintenance window, otherwise it will be done immediately. There will be no changes to the connection information after resizing.
