### Describe the bug When doing a grouping set on columns with null values we produce the incorrect result. ### To Reproduce Run the following in query in datafusion-cli ``` > CREATE TABLE integers_with_nulls (value INT) as VALUES (1), (NULL); 0 row(s) fetched. Elapsed 0.016 seconds. > SELECT value, min(value) FROM integers_with_nulls GROUP BY CUBE(value); +-------+--------------------------------+ | value | min(integers_with_nulls.value) | +-------+--------------------------------+ | 1 | 1 | | | 1 | +-------+--------------------------------+ ``` ### Expected behavior The expected bevahior is that the null in the data creates a different group from the nulls from the grouping set. The exected results are ``` > SELECT value, min(value) FROM integers_with_nulls GROUP BY CUBE(value); +-------+--------------------------------+ | value | min(integers_with_nulls.value) | +-------+--------------------------------+ | 1 | 1 | | | 1 | | | | +-------+--------------------------------+ ``` This is the behavior in PostgresSQL, Spark and DuckDB (and most likely other query engines). ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
