We are using postgresql 8.2.17 on Gentoo
Our postgresql database stopped working with the error
ERROR: could not open relation 1663/26468499/26470404: No such file or
directory
After one minute of these errors on every statement run we had what
looks like a memory failure:

We cannot connect to the database using psql as it gives the could not
open relation error. We ran fsck and did not find any problems. I
searched through google and found suggestions such as reindex, but we
can't connect to the db. We also can't take a backup of the
database as
pg_dump gives the same error.
Does the not connect also apply to starting postgres in single user
mode?
Same error with single user mode.
postgres --single -D /var/lib/postgresql/8.2/data clstock
FATAL: could not open relation 1663/26468499/1259: No such file or
directory
Well it is failing on a different relation. Is the FATAL message
correct, are the relations shown in fact not on the file system?
Throughout the log, I noticed a bunch of different relations that are
missing.
It seems to me that they are not in the file system.
data/base/26468499 exists with a large number of files, but the ones it
mentions are not there.
This is our production database and crashed at the end of the day. If
possible, I would really not like to lose a full days work by
restoring
yesterdays backup.
Thanks
Sim
