We haven't seen any other reports of this that I can recall, so I'm
leaning towards the bad-hardware theory, but I never like blaming
problems on hardware. Next time it happens, would you shut down the
postmaster and make a copy of pg_attribute and its indexes (the physical
files) to send to me, before you reindex? Eyeballing the remains might
give some evidence one way or the other.
