mongoose just failed with almost the exact same symptoms:
It's not quite the same diffs, which is unsurprising given the presumed
mechanism behind the failure, but that probably shoots down the "add
another expected file" response.
I imagine some recent change has made the probability of this behavior
much higher than it was before; perhaps there's more pg_constraint
update traffic in concurrent tests? Anyway, it's now up to "must fix"
in my estimation. I'll look into the new-pg_constraint-index idea.
I think someone should also take a hard look at that idea of introducing
more timing variability into the parallel tests. Any volunteers?
