* Removed explicit cast from `BOOLEAN` to numeric types and vice versa
  (gh-4770).

* Removed explicit cast from `VARBINARY` to numeric types and vice versa
  (gh-4772, gh-5852).

* Fixed a bug due to which a string that is not `NULL` terminated could not be
  cast to `BOOLEAN`, even if the conversion should be successful according to
  the rules.
