### Describe the bug The code checks the input schema to determine if a column is nullable. However, for grouping sets, even a column created from a non-nullable expression will become nullable. ### To Reproduce * Create a query plan with a non-nullable output column * Create an aggregation with a grouping set containing the output column * Check the output schema - the column will be non-nullable ### Expected behavior The output column will be nullable. ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
