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. Konstantin -- Dipl-Inf. Konstantin Agouros aka Elwood Blues.
