Thread: pgsql: Correct type of front_pathkey to PathKey

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.
