Hmm, the buildfarm client does this at the beginning of each run to
remove anything that might be left over from a previous run:

rmtree("inst");
rmtree("$pgsql") unless ($from_source && !$use_vpath);

Do I need to precede those with some recursive chmod commands? Perhaps
the client should refuse to run if there is still something left after
these.

cheers
