Oddly enough, "adder" just showed this same failure [1]:

and that's not in the test_plan_advice run at all, but pg_upgrade's
run of the core regression tests. I wonder if we recently made some
seemingly-unrelated change that has increased the probability of
having a 'v' in the right byte. Anyway, you should get this fix
pushed.
