I get this error.  Is this hardware related or could it be something 
with the postgresql.conf settings.
I changed them for performance reasons.  (More memory, more wal 
buffers).
There are 2 databases.  One got the error yesterday, I dropped it (was 
brand new), recreated it and the error was gone.
Now the error is there again on another database.

Personally, I think it's a HD error.

Met vriendelijke groeten,
Bien à vous,
Kind regards,

It's a hardware failure --- bad disk block, likely.  You might find more
details in the kernel log (/var/log/messages or equivalent).
