I did wonder if you'd want to see uses of FILTER in there as I'm thinking that should really be covered by the core patch and the tests here really should just be checking the inverse transition functions for min and max.
As for the data types tested, I ended just adding tests for int and text for min and max. Let me know if you think that more should be tested.
As for bool_or and bool_and. I didn't think there was much extra that would need tested after I added 1 test. It's pretty simple code and adding anything extra seems like it would be testing something else.
