Already downloaded - the upgrade is on the todo list.

I successfully tested then ran a process to dump the db, drop it, then
restore it. All is fine, now. I think the bad block wasn't used by
anything important as the server continued handling all its work
without problem. The only time this error showed up in the log was
when I tried to query the table or when autovacuum tried to analyze
it.
Fortunately this database dump is only ~300MB so I only had to shut
down for 5 minutes to do the dump/drop/create/restore.
