The first time this happened, I chalked it up to some kind of disk
corruption based on the mailing list archives. So I dumped the
databases, did a fresh initdb, forced an fsck (these run with a jfs
data partition and an ext2 wal partition) which found no problems and
then reloaded the databases.
Now about a week later
Unless you actually executed 2565134864 transactions in that one week,
this is still data corruption.
Check for faulty memory.
I'd be more inclined to agree with you if it happened on only one
server machine. But this has now happened on two different machines
in the space of a week.
My understanding is that the transaction id logged is garbage because
the bookkeeping fields have been clobbered for some tuple(s). The one
last week was really low (like < 1000).
