Troubleshooting why a file on your filesystem was corrupt/torn after the fact
when no logs or traces of evidence exists is next to impossible.  In this case
there isn't even an errno set from the system.  A good place to start would be
to upgrade your system as you are several bugfix releases behind.

The PostgreSQL website lists several professional services companies who offer
support contracts with SLA's which this list doesn't, and who can be hands-on
to investigate should this ever happen again.
