Обсуждение: vacuum fails with 'invalid page header' message
We had a vacuum fail recently with the following error: invalid page header in block 846 of relation "move_pkey" Anyone have an idea what could cause this problem and what we need to do to resolve it?

Yes, reindex might fix it. But more than likely there's a problem with your hardware somewhere, and it needs to be checked out carefully for problems. i.e. bad hard drive, memory, cpu, etc...

After reindexing the table, vacuum full completes successfully. Would this be an indication the reindexing corrected the problem? Anything else the could possibly cause this problem? The sys admin is doubtful it's hardware related. We don't see any errors in the system logs to indicate there's a problem. Is it possible that our application could cause such corruption? -- Until later, Geoffrey Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety. - Benjamin Franklin
