MDEV-19956 Queries with subqueries containing UNION are not parsed Shift-Reduce conflicts prevented parsing some queries with subqueries that used set operations when the subqueries occurred in expressions or in IN predicands. The grammar rules for query expression were transformed in order to avoid these conflicts. New grammar rules employ an idea taken from MySQL 8.0.
