The maintenance period will begin on 2026-09-14 06:00:00 and conclude on 2026-09-21 06:00:00.

During this time:

• Instances will restart within their scheduled maintenance window.
• No action is required.
• Services with HA replicas will not experience downtime but will undergo a single switchover event during maintenance, lasting only a few seconds.
• To prevent downtime during this event, consider adding an HA replica to your service.

As part of this maintenance, a new minor version of PostgreSQL will be installed. The corresponding minor version for your current major version will be applied.

Minor versions included in this update

• 18.6
• 17.11
• 16.15
