The method of TiDB dashboard login authentication is sql user authentication, tidb4pg is compatible with PgSQL user authentication and abandons the original MySQL authentication.

We didn't modify the user authentication code in other TiDB component, so the sql user authentication will fail.

We will consider whether to modify tidb4pg or other components to solve this problem in the future, but it may take some time.
