Errors like this are usually caused by hardware problems.  I think
the second-most common cause is running in a configuration with
fsync = off or full_page_writes = off, and suffering a power outage
or OS crash.  I would recommend that you check your configuration
for these unsafe settings and schedule a check of your hardware and
drivers.
