New rule: Always specify column names instead of expressions in GROUP BY clauses. #202
Description
Starting with 23c it is possible to group by column alias or position.
The use of a position should be avoided. It's handled in #197.
With 23c it is no longer necessary to repeat expressions in select_clause. The column alias should be used instead. In improves readability and maintainability.
