I went looking at this tonight and then found your message. I think
the reason we're not seeing a lot of these in the buildfarm is that
not that many animals are running this test suite (it requires putting
xid_wraparound in PG_TEST_EXTRA). I concur with your conclusion that
poll_query_until is iterating the INSERT an extra time, but I think
a less magic solution would be to just change the test's match rule
to allow that to happen, more or less as attached.
