Обсуждение: ERROR: invalid page header in block 24555 of relation "logs_20080425"

Hi,

I am getting the above error. Can I do anything to fix this? I can get most of the data in the table but queries that
gopass that block don't work. Is there a way to recover more of the data in the table? 

I am running PostgreSQL 8.1.11 on Linux.

Thanks
