This is definitely some sort of disk problem. Either you've written
bad data to the disk in some way, or else the disk is corrupted or
damaged.
If it is a hardware problem, the obvious suspects are memory (I'd
discount this idea unless everything else doesn't check out), a disk
failure, or a controller failure.
It could be OS related as well. Several of the 2.4 Linux kernel
series, for instance, had roblems with massive filesystem corruption.

How did you check?

When is your most recent backup? If you can't pg_dump, you will be
needing that backup.

So you re-installed the data set on a machine that had somehow
failed, you don't know why, and hoped that the problem would
solve itself? Uh, that wasn't a good idea. In the future, if you
have a problem which people suggest might be, for instance, a bad
disk, it'd be a _very good_ idea to figure out precisely what the
problem is before relying on the identical hardware again.
