invalid page header on postgres using gpt/dkctl

[Derrick Lobo <derrick.lobo%givex.com@localhost>]

Hi All

I get a "invalid page header" on postgres .

The servers uses 3 x 2Tb drivers and I used gtp/dkctl to configure a
disk.. The server has a LSI controller and the DISK are SATA. 

I DO NOT see any error messages on dmesg or /var/log/messages.... however
my database keeps getting corrupt.. 

Using dkctl I am unable to fix or find any badsectors.

The commands used to configure the disk was

# gpt show sd0
        start         size  index  contents
            0            1         PMBR
            1  11714691071
