> what if SELECT ALL NULLIF (-98, NULL) AS col0 ? The right result of nullif(-98, null) is -98. but before fix the bug, the answer is `null`. Because the FE wiil treat all the function not in `non_null_result_with_null_param_functions` alwalys `null` if there params have `null`. so add the `nullif` function to `non_null_result_with_null_param_functions` we can get the right answer:`98` -- This is an automated message from the Apache Git Service.
