## Which issue does this PR close? Closes #5647. ## Rationale for this change Implements the GROUPING function as per Postgres. https://www.postgresql.org/docs/15/functions-aggregate.html#FUNCTIONS-GROUPING-TABLE This is in contrast to other implementations including Databricks and Oracle where GROUPING takes only one column and there is a GROUPING_ID function that yields a similar bitfield. ## What changes are included in this PR? Implement the aggregate function in the Physical Planning stage. ## Are these changes tested? A few unit tests and an integration test provided by @ JasonLi-cn in a previous unfinished PR. Could always use more. ## Are there any user-facing changes? * Slight change to definition of unimplemented function. * Implementation of that function. -- This is an automated message from the Apache Git Service.
