Comment(by pramsey):
Implementation here has also taken in aspects from #2101, to allow easier
testing and verification of results. I'm quite happy with the constant
selectivity estimates in my tests so far, and the join selectivity is if
nothing else more sensitive to actual data distribution than before. All
tests pass, including a couple tests for selectivity itself!
