The table corruption bugs were triggered when the load was very high, as far as I know. It happened twice to me. In both cases, the corruption couldn't be corrected.
The worse part was the corruption was propagated into replica, which brought up much more serious issue with Postgres's replication model. So the only solution was to install the latest good backup.
