FATAL: cache lookup failed for access method 6881280

-----BEGIN PGP SIGNED MESSAGE-----

I'm getting this message when I try to access one of the databases in
my cluster:

FATAL: cache lookup failed for access method 6881280

I get the message any way I try to access it: remotely via TCP,
locally on the db server, as well as with a single-user mode postgres
command.

Any ideas what could be the cause, or what I could do to fix it? All
the other (30+) databases in the cluster appear to be perfectly fine.

Thanks,

Brock
