 I suppose this is the first ticket for PHP 8.1 - Exciting :)

 In PHP 8.1, the default error reporting is set to always throw an
 exception, as opposed to emitting a warning. WordPress gracefully handles
 the database errors by inspecting the error codes.

  - [https://php.watch/versions/8.1/mysqli-error-mode PHP 8.1: MySQLi:
 Default error mode set to exceptions]
  - [https://wiki.php.net/rfc/mysqli_default_errmode RFC]

 I suggest that WordPress set the error reporting mode to off, which is the
 default value prior to this change. Unless we do this, any bad MySQLi
 connection will throw an exception, leading to a WSOD, or a blank page
 with the uncaught exception error.
