Managed Postgres handles PostgreSQL version upgrades to keep your instances secure and up to date. Both minor and major version upgrades are supported with minimal disruption.

​
Maintenance updates

Regular maintenance in the PostgreSQL instances includes the following:
  • Minor version upgrades (e.g., 17.4 to 17.5) include bug fixes and PostgreSQL engine security patches.
  • Managed Service features. Improvements to native CDC, observability, pg_clickhouse, and other extensions.
  • Operating system and system components patches. Including security fixes, efficiency, and other improvements.
These are performed via failover and typically result in only a brief disconnect, often lasting just a few seconds. For instances with standbys enabled, the upgrade is applied to the standby first, followed by a failover to minimize downtime.

​
Maintenance windows

Default maintenance window is 14:00 to 16:00 UTC on Sunday. Expected downtime is less than 1 minute within the window. For Enterprise Tier organizations, Managed Postgres supports maintenance windows so that upgrades and other maintenance operations can be scheduled at a time that’s least disruptive to your workload. UI and API support for configuring maintenance windows is coming soon. In the meantime, contact support to set up a maintenance window for your instance.

​
Major version upgrades

Major version upgrades (e.g., 17.x to 18.x) via UI and API are coming soon. In the meantime, contact support to upgrade your Managed Postgres instance.
