Yech.  So much for RAID reliability ... maybe you need to reconfigure
the array for more redundancy?

Given that it's just a backup machine, it's probably not worth heroics
to try to recover.  I'm not sure that you could trust any data you got
out of it, anyway --- corrupted pg_clog is likely to lead to
inconsistency in the form of partially-applied transactions, which can
be hard to detect.
