pepijnve opened a new issue, #18626:
URL: https://github.com/apache/datafusion/issues/18626
### Describe the bug
The current implementation of `apply_operator` does not implement all
possible cases of 'and' and 'or' correctly
### To Reproduce
There are quite a few cases that are not correct. One example is
```
let t = NullableInterval::NotNull { values: Interval::CERTAINLY_TRUE };
let u = NullableInterval::Null { datatype: DataType::Boolean };
t.apply_operator(&Operator::Or, &u).unwrap();
```
In SQL `true OR NULL` evaluates to `true`, so this should return the same
value as `t`. In practice the same value as `u` is returned.
### Expected behavior
The interval arithmetic for boolean `NullableInterval` matches SQLs boolean
arithmetic.
