Hm, what I was expecting to see is that RI_FKey_check_ins and
RI_FKey_check_upd get marked as proparallel = 'r' and the remainder
get marked as proparallel = 'u'. Remember that the default for
builtin functions is proparallel = 's', but surely that's wrong
for triggers that can propagate updates to other tables?
