Invalid page header in block...

Hi,

I have a machine that is currently a bit unstable. No I got a:
sysad=# select * from attacks where start < '1.1.2000';
ERROR: Invalid page header in block 3618 of attacks

From googeling I saw that this should be solvable if I can delete the bad rows
or find the bad datafile. Anybody has a tip on how to do that? Because I could
not find the how in detail.

The whole thing is 7.3.6 on Gentoo Linux.
