TencentDB for PostgreSQL allows you to upgrade kernel minor version, so you can use new features, improve performance, or fix issues.
Overview
You can manually upgrade kernel minor version in the console.
Upgrade Rules
If an instance to be upgraded is associated with other instances (e.g., read-only instances), these instances will be upgraded together to ensure data consistency.
TencentDB for PostgreSQL upgrade may involve data migration. The time it takes to migrate an instance depends on the data size of the instance. Your business will not be affected during the upgrade and can be accessed as per usual.
Note
Instance switch will be required after kernel minor version upgrade is completed, that is, the database may be disconnected for seconds. We recommend that you use applications configured with automatic reconnection feature and conduct the switch during the instance maintenance window.
The kernel minor version cannot be downgraded once upgraded.
Directions
1. Log in to the TencentDB for PostgreSQL console. In the instance list, click an instance ID or Manage in the Operation column to enter the instance details page. 2. In the Configuration Info section, click Upgrade Kernel Minor Version.
3. In the pop-up window, set the target version to upgrade and click OK.
Note:
As database kernel minor version upgrade may involve data migration, a momentary disconnection from the database may occur after the upgrade is completed. We recommend that you set the switch time to During maintenance time, so that the switch will be initiated within the next maintenance time after the upgrade is completed.
