Description:

https://www.postgresql.org/docs/14/functions-comparison.html

See the heading: "Table 9.2. Comparison Predicates"

"2 BETWEEN 3 AND 1 → f" # ok this is false.

But let's read the example immediately below (the 'not between' example)

2 NOT BETWEEN 1 AND 3 → f   # what? This is also false. how can the negation
also be the same value? I would expect it to be true?

That doesn't seem right?
