Another thing that's annoying about this is that it doesn't give you any 
idea of how it's failing if there's a database difference. All we get is:

    Files /home/pgrunner/bf/root/HEAD/pgsql.3188/contrib/pg_upgrade/tmp_check/dump1.sql and /home/pgrunner/bf/root/HEAD/pgsql.3188/contrib/pg_upgrade/tmp_check/dump2.sql differ


See 
<http://www.pgbuildfarm.org/cgi-bin/show_log.pl?nm=frogmouth&dt=2011-11-28%2019%3A30%3A03> 
for an example. For buildfarm purposes this is pretty low grade info, ISTM.
