Review comment:
       In general, we should only use one unit test case for one specific test purpose. It's better to split this test case into two cases, one is testing `SavepointFormatType.DEFAULT` and another is for `SavepointFormatType.NATIVE`.
   
   Moreover, I also suggest to test `SavepointFormatType.CANONICAL` instead of `SavepointFormatType.DEFAULT` in case we might change the `SavepointFormatType.DEFAULT` to `SavepointFormatType.NATIVE` in the future.
