Make sure the result of a CASE expression is nullable if (and only if)
at least one of the result expressions is nullable.

> This JUnit test code fails because it detects that the query returns null even though
the result column is reported as not nullable:
> {code}
>         PreparedStatement ps = prepareStatement(
>                 "values case when false then 1 else ? end");
>         ps.setNull(1, Types.INTEGER);
>         JDBC.assertSingleValueResultSet(ps.executeQuery(), null);
> {code}
