Re: incorrect checksum detected on "global/pg_filenode.map" when VACUUM FULL is executed

John, Michael,

Thanks for suggestion for upgrade. I know that's the way to go, but it's not so easy due to circumstances on my side.

Meanwhile, could you tell me what is this "global/pg_filenode.map" for?

Regards,

Tatsuki

Yep, this is mandatory. You are taking a lot of risks here by only using 9.2.4.
