Set a PostgreSQL Maintenance Window

If you do not choose a maintenance window during the creation of your database, a system-defined maintenance window will be assigned to your database. You can update the window at any time, as shown in the example. For more information, see Maintenance Window.

Endpoint

Use the following endpoint to set a PostgreSQL maintenance window:https://api.ionos.com/databases/postgresql/clusters/{clusterId}

Note: The sample UUID is 498ae72f-411f-11eb-9d07-046c59cc737e.

Caution: When your cluster contains only one replica, you may experience a short downtime during this maintenance window while your database instance is being updated. In a replicated cluster, we only update standbys; however, we may perform a switchover to change the leader node.
