If we're going to keep them in vacuum.sql, we should use the
client_min_messages fix there, as that's a full solution not just
reducing the window.  But I don't agree that these tests are worth
the cycles, given the coverage elsewhere.  The probability of breaking
this option is just not high enough to justify core-regression-test
coverage.
