>
> IN clause provides better statistics estimation since predicates are equality
> based and it keeps into account selectivity of all values. BETWEEN is
> rewritten into {{>= AND <=}} i.e. non-equality predicates which cause worse
> estimation. For integer types BETWEEN could be rewritten into IN e.g. BETWEEN
> 4 and 7 is equivalent to IN (4,5,6,7).
