> @Dandandan @alamb i wonder if you think defining lt et. al. makes sense
here, if we allow false < true. if that's defined then i can simplify this
branch
I personally think it does make sense to define the other logical comparison
operators for `BooleanArray` (even though the usecase for `bool` < `bool` is
limited). My primary rationale is for completeness (SQL and Postgres allows for
it) and I do think it will avoid having to special case boolean columns for
features like DataFusion partition pruning (which converts `=` into `<=` and
`>` comparisons for comparing to statistics)
```
alamb=# select true < false;
?column?
