    Description

      The SQL parser allows invalid MERGE statements with mismatched parentheses. For example, the following invalid statement is treated as valid but is missing a trailing ')':

      merge into emps as e
      using temps as t on e.empno = t.empno
      when not matched
      then insert (a, b) (values (1, 2);
      

      And the following invalid statement is treated as valid but has an unmatched trailing ')':

      merge into emps as e
      using temps as t on e.empno = t.empno
      when not matched
      then insert (a, b) values (1, 2));
