If you know which tuple it is that kills it, you can delete it. That should
be sufficient. If you know the ctid or oid, they're good keys for this sort
of thing.

I strongly recommend memtest86[1]. It runs from a floppy and is very good at
picking up memory errors. After that check out your hard disk with whatever
program your HDD manufacturer provides. But memory is the most likely.
Just in case, open the case and check for dust buildup and loose cables.
