      Description

      The following query implicitly converts a character literal to a date literal; it passes validation but fails during code generation.

      select *
      from "scott".emp
      WHERE hiredate = '1980-12-17';
      +-------+-------+-------+------+------------+--------+------+--------+
      | EMPNO | ENAME | JOB   | MGR  | HIREDATE   | SAL    | COMM | DEPTNO |
      +-------+-------+-------+------+------------+--------+------+--------+
      |  7369 | SMITH | CLERK | 7902 | 1980-12-17 | 800.00 |      |     20 |
      +-------+-------+-------+------+------------+--------+------+--------+
      (1 row)
      
      !ok
