Even if this had not failed in the buildfarm, it would certainly
have caused problems for somebody.  We have a very strong rule
that you *do not* make regression test results dependent on exact
computed cost or rowcount values, because those are inherently
platform-dependent.  I do not understand how you thought that
pg_overexplain might be exempt from that problem.
