Setting Instance Parameters

Last updated: 2021-11-29 10:23:31

    You can view and modify certain parameters and query parameter modification logs in TencentDB for PostgreSQL console.

    Notes

    • To ensure instance stability, only some parameters can be modified in the console. These parameters are displayed on the Parameter Settings page.
    • If the modified parameter requires instance restart to take effect, the system will ask you if you wish to restart. We recommend that you do so during off-peak hours and ensure that your application has a reconnection mechanism.
      Note:

      Some are key parameters, modifying which may affect your use or the normal running of the instance. Therefore, exercise caution when modifying key parameters.
