My bet is that this is actually a corrupt-data problem ... unless you
actually have any 875MB fields in your table. The implication is that
the length word of a variable-width field contains garbage. More than
likely, the whole tuple is garbaged, but this happens to be the first
visible symptom.

There is plenty of discussion of recovering from data corruption in
the archives, so go have a look.

Might want to think about an update sometime, too ;-)
