hi again

i've stopped postgres and done this
dd if=16403.3.orig of=16403.3 bs=8192 count=109541
dd if=/dev/zero bs=8192 count=1 >> 16403.3
dd if=16403.3.orig skip=109542 bs=8192 >> 16403.3

then started postgres, but did not help, the same error appears.
ERROR:  invalid page header in block 502758 of relation base/16388/16403

am i doing anything wrong?

regards, fous
