In AnalyticDB for PostgreSQL, you can change the connection address of an instance. For example, if you switch your service to a different AnalyticDB for PostgreSQL instance, you do not need to modify the application. You only need to configure the new instance to use the connection address of the old instance.


  • The instance is running.
  • The instance has set up a whitelist.


  1. Log on to the AnalyticDB for PostgreSQL console.
  2. Select the Region of the instance.
  3. Locate the target instance. In the Actions column, click Manage.
  4. In the left-side navigation pane, click Database Connection.
  5. On the Database Connection page, click Modify Connection Address.
  6. In the dialog box displayed, click Connection Type and select a network type.

    You can select Intranet Address or Internet Address. The Internet Address option is only available after you have applied for a public IP address.

  7. Enter the relevant information in Connection Address and Port, and click OK.

    After the page is refreshed, the new connection address is displayed.
