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.
