Hmm, that makes it sound like a plain old data-corruption problem, ie,
trashed xmin or xmax in some tuple header. Can you do a "select
count(*)" from this table without getting the error?

[ raised eyebrow... ] You're keeping important data in an RC version
that you've not updated for more than a year? Your faith in Postgres'
code quality is touching, but I'd counsel getting onto a more recent
release.
