Hi Antonios,

Don´t is 'header' ? what is your real problem ?

Message with HEADER generally occurs when you it had a badly recorded page
in the system of archives.

The Database shutdown before occurring this message ?

Another possible cause it would be a memory or damaged disk (in this order
of diffidence).

Go to the solutions:

1. Enable zero_damaged_pages in pg_settings catalog. With this setting
enable the PostgreSQL server
erases all defective pages in your table. YOU CAN LOSE INFORMATON WITH THIS.

OR

2. Try find the register(s) defective. Do you can make this for sampling
with
(SELECT * FROM tab LIMIT x OFFSET y). After to find the register(s)
defective,
use the xlogdump utility (http://xlogviewer.projects.postgresql.org/docs/)
to see the data
and insert new other row and to erase the old one.

I wait to have helped
