Hold it right there, full stop.

If you've got corruption you've either found a rare corner case in 
postgresql (unlikely, corruption is not usually a big problem for 
postgresql) OR you have bad hardware.  Test your RAM, CPUs, and hard 
drives before going any further.   Data corruption, 99% of the time, is 
not the fault of postgresql but the fault of the hardware.
