Domain name for API request: postgres.tencentcloudapi.com.
This API is used to upgrade the major kernel version of an instance, for example, from PostgreSQL 12 to PostgreSQL 15.
A maximum of 20 requests can be initiated per second for this API.
The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.
| Parameter Name | Required | Type | Description |
|---|---|---|---|
| Action | Yes | String | Common Params. The value used for this API: UpgradeDBInstanceMajorVersion. |
| Version | Yes | String | Common Params. The value used for this API: 2017-03-12. |
| Region | No | String | Common Params. This parameter is not required for this API. |
| DBInstanceId | Yes | String | Instance ID. |
| TargetDBKernelVersion | Yes | String | Target kernel version number, where upgradeable target kernel version numbers can be acquired through API DescribeDBVersions. |
| UpgradeCheck | No | Boolean | Whether it is verification mode: if UpgradeCheck is True, it means only kernel version compatibility check will be conducted, without actual upgrade operations, and there will be no affect on the original instance. The check results can be viewed through the upgrade logs. |
| BackupBeforeUpgrade | No | Boolean | Pre-upgrade backup option: True means a full backup is required before upgrade, and False means a full backup is not required before upgrade. If there is an existing backup set that can restore the instance to its pre-upgrade state, False can be selected; otherwise, True should be specified. This parameter is invalid when UpgradeCheck is True. |
| StatisticsRefreshOption | No | Integer | Statistics collection option, which is used to run ANALYZE on the primary instance to update system statistics after the upgrade. Valid values include: 0: No statistics collection required; 1: Collect statistics before instance recovery write; 3: Collect statistics after instance recovery write. This parameter is invalid when UpgradeCheck is True. |
| ExtensionUpgradeOption | No | Integer | Plugin upgrade option. pg_upgrade does not upgrade any plugins, and "ALTER EXTENSION UPDATE" needs to be executed on the database where the plugins were created after the upgrade. When initiating a major version upgrade of an instance, you can specify whether the upgrade task automatically upgrades the plugin version before/after the instance recovery write. Valid values include: 0: No automatic plugin upgrade required; 1: Upgrade plugins before recovery write; 2: Upgrade plugins after recovery write. This parameter is invalid when UpgradeCheck is True. |
| UpgradeTimeOption | No | Integer | Upgrade time option. During the upgrade process, there will be a period when the instance is read-only, and there will be a second-level flash disconnection. When initiating an upgrade, you need to choose the time window for this impact. Valid values include: 0: Execute automatically, no specific time window required; 1: Specify the time window for this upgrade task, which is set via UpgradeTimeBegin and UpgradeTimeEnd parameters; 2: Execute during the instance operation and maintenance time window. This parameter is invalid when UpgradeCheck is True. |
| UpgradeTimeBegin | No | String | Upgrade window start time, and the time format is HH:MM:SS, for example: 01:00:00. This parameter is valid when UpgradeTimeOption is set to 1.This parameter is invalid when UpgradeCheck is True. |
| UpgradeTimeEnd | No | String | Upgrade window end time, and the time format is HH:MM:SS, for example: 2:00:00 AM. This parameter is valid when UpgradeTimeOption is set to 1.This parameter is invalid when UpgradeCheck is True. |
| Parameter Name | Type | Description |
|---|---|---|
| RequestId | String | The unique request ID, generated by the server, will be returned for every request (if the request fails to reach the server for other reasons, the request will not obtain a RequestId). RequestId is required for locating a problem. |
The current major version number of the instance is 10. If you need to use features related to PostgreSQL 15, you can upgrade the kernel version of the instance from 10 to 15 through the major version upgrade feature, and perform the upgrade within a specified time window.
