I've updated Jeff Janes' test suite to support testing of exclusion
constraints that are equivalent to unique indexes:
https://github.com/petergeoghegan/jjanes_upsert/commit/a941f423e9500b847b1a9d1805ba52cb11db0ae9
(This requires a quick hack to the Postgres source code to accept
exclusion constraints as ON CONFLICT UPDATE arbiters).
So far, everything seems okay with exclusion constraints, as far as I
can determine using the stress tests that we have. This is an
encouraging sign.
