I'm wondering about hardware problems --- how sure are you that you
don't have flaky RAM or a bad disk drive?
Also, what locale settings are you using in the database (use
pg_controldata to verify this)? It seems possible that a broken
locale definition could mess up indexes.
I know the above sounds like passing the buck, but when you're the only
one reporting such troubles, I have to ask what's different about your
installation ...
