8.0.7 and 8.1.3 are the latest versions in their respective branches;
those are the versions to run to get the latest bug fixes.

Beats me; it could be any or all of them. Certain filesystem and
hardware configurations are more prone to data corruption than
others, especially in the event of a system crash, so those are
among the usual suspects. One reason to look at the data in the
bad block is to see what's there: if you see data that obviously
came from outside the database then that would tend to exonerate
PostgreSQL.
