Database corruption

I am running 8.3.3 currently on this box.
Last week we had a database corruption issue that started as:

Aug 24 07:15:19 iprobe028 postgres[20034]: [3-1] ERROR: could not read
block 0 of relation 1663/16554/7463400: read only 0 of 8192 bytes

We renamed and recreated the database that it was complaining about, and the
error started up again with the new database within the hour. We move the
database to a different disk, with the same results. The only way to fix it
was to do a complete initdb on the box.

Tom:
I did not see anything that might have been fixed in the 8.3 release notes
that might be this issue. I know this is an old version, but I have 2
copies of the data directory that should have the error if you (or whoever
you delegate) would like to see them before I remove them. I don't have an
issue with sending the cluster data off list if it might be useful.

Thanks,
Woody
