Correct type of front_pathkey to PathKey In sort_inner_and_outer we iterate a list of PathKey elements, but the variable is declared as (List *). This mistake is benign, because we only pass the pointer to lcons() and never dereference it.
This exists since ~2004, but it's confusing. So fix and backpatch to all supported branches.
