Hi Andrew and Andy. This behaviour dates back to the [initial](https://github.com/apache/arrow/pull/9364) implementation, so I can try to provide some context. The [select_with_having](https://github.com/apache/arrow-datafusion/blob/6786203ea8c9c4cfe604f74a5cece8e829fb56c8/datafusion/core/src/sql/planner.rs#L2818) and [select_with_having_referencing_column_not_in_select](https://github.com/apache/arrow-datafusion/blob/6786203ea8c9c4cfe604f74a5cece8e829fb56c8/datafusion/core/src/sql/planner.rs#L2829) cases are there, almost certainly, because those queries are valid in MySQL 8. I used both Postgres and MySQL as a reference for the implementation, and in this particular case, opted for the MySQL behaviour, since it's the more permissive of the two. I think since then, Postgres has been adopted as the reference. -- This is an automated message from the Apache Git Service.
