Sounds like what we in Oracle land would call a corrupt block.  It also sounds like it's an index block that got messed up.  I'd try dropping and rebuilding the index if possible before hitting the panic button.  As a quick check try selecting all of the rows out of the table without a where clause.  If that succeeds you can be assured that data is safe, just the index got trashed.  Therefore, drop the index, vacuum the table, and rebuild the index.

Input/output error suggests that you urgently need a new disk.
