I think the problem is probably that Peter ignored this bit of advice
in parallel_schedule:
# rules cannot run concurrently with any test that creates
# a view or rule in the public schema
when he inserted "collate.linux.utf8" concurrently with "rules".
(I suspect BTW that the point is not so much that you better not
*create* such an object, as that you better not *drop* it concurrently
with that query.)
