Restarting Instances

Last updated: 2021-05-18 17:16:25

    Restart is indispensable to the maintenance of databases. Restarting a PostgreSQL instance is equivalent to restarting a database (service and process) on a local server.


    • Please exercise great caution when restarting a database, which plays a vital role in the business. Before the restart, it is recommended to disconnect the database from server and stop writing data.
    • Restarting an instance does not change its physical attributes, so the public IP, private IP, and any data stored on the instance will remain unchanged.
    • After the restart, reconnection to the database is needed. Please make sure your business has a reconnection mechanism.
    • Be sure to restart the instance during off-hours so as to ensure success and reduce impact on your business.


    1. Log in to the TencentDB for PostgreSQL console, locate the desired instance in the instance list, and click More > Restart in the Operation column.

      • Generally, it takes a few seconds to minutes to restart an instance, during which the instance cannot be accessed and existing connections to it will be closed.
      • Restart will fail if there are a large number of writes and dirty pages during the restart. In this case, the instance will roll back to the status before the restart and can still be accessed.
      • There is a chance of failure in restarting a database. If it takes more than 10 minutes to restart, you can submit a ticket for help.
    2. In the pop-up dialog box, indicate your consent and click Confirm.
