Azure Database for PostgreSQL – Hyperscale (Citus) now allows you to specify a maintenance schedule for each server group, with a system-managed schedule as the default. With system-managed schedules, server group maintenance will be scheduled between 11:00 PM and 7:00 AM in the region’s time where the server group is created on a system-selected day of week. Custom schedules allow you to specify a preferred day of the week and a 30-minute window within that day for when maintenance for that server group will start.
Whether a system-managed or custom schedule is selected, each server group will have:
- A notification posted to Azure Service Health five days before the actual maintenance event
- At least 30 days after the initial server group creation date
- At least 30 days between successful maintenance events
