If you are using the EnterpriseDB release, and paying for support, you can always take this to them.

Subject: [GENERAL] Re: [GENERAL] ERROR: XX001: could not read block 235 4 of relation…
We are using EnterpriseDB PostGresql 8.3. I can't simply take a good backup because weeks have pass since the first error occurs.
I will try to Vacumm Full first, if nothing is fixed, I will try to pg_dump like you suggest.

Try to do a pg_dump of the database or clean (no delete) del wal files
(this is not
recommendable for new users).
