Ok, throwing a few "random" questions in your direction:
What procedure did you use to do those upgrades? Maybe something went
wrong there? I'm assuming you upgraded using dump/restore, or
postgres would have complained about the version of the data files at
startup, but maybe you did something unusual.
Are you sure there's only one version of postgres running?
Are all your libraries up to date, no old versions hanging around
where they should have been replaced?
Do you have any stored procedures in C? If so, do you perhaps use
malloc/free instead of the ones Postgres provides (reasoning you may
be freeing a reference to the toast table somehow)?
Is that data-file on a mirror where one part of the mirror may be
mirroring a bad sector over the good one on the other drive(s)?
I may be talking nonsense, I'm no Tom Lane, but I know a fair share
about postgres ;)
If you can't see the forest for the trees,
cut the trees and you'll see there is no forest.
