As far as I know it is possible to have third-party modules that extend
the buildfarm client script so that it runs additional tests that the
standard ones.  You could have a custom module installed in some
powerful machine of yours that runs the WAL consistency check and report
the results to the buildfarm.  A single animal running that test should
be enough, right?
