I think if you wait_for_prior_commit() also for secondary key case, you
should definitely restrict it to be only for conservative parallel
replication, not for optimistic/agressive. Using a secondary key seems
generally fine (as opposed to full table scan), and this problem should
affect only conservative mode, no need to penalise optimistic/aggressive.
(But maybe that is what is meant with "DRAFT").
