Suggested rule

Azure Database for PostgreSQL flexible servers undergo periodic maintenance to ensure your managed database remains secure, stable, and up-to-date. This maintenance includes applying security updates, system upgrades, and software patches.

Maintenance windows can be scheduled in two ways for each flexible server:

• System-Managed Schedule: The system automatically selects a one-hour window between 11 PM and 7 AM in your server’s regional time.
• Custom Schedule: You can specify a preferred maintenance window by choosing the day of the week and a one-hour time window.

By configuring a customer-controlled maintenance window, you can schedule updates to occur during a preferred time, ideally outside business hours, minimizing disruptions.
