If I got an error like this when trying to dump a db from the mangled
data directory is it safe to say it's totally hosed or is there some
chance of recovery?
pg_dump: ERROR: could not open relation 1663/18392/18400: No such file
or directory
pg_dump: SQL command to dump the contents of table "file" failed:
PQendcopy() failed.

pg_dump: The command was: COPY public.file (vfs_id, vfs_type, vfs_path,

What happens when you fsck the relevant partitions?
Errors about a bunch of duplicate inodes, missing inodes, etc. Should I
do it again and get some of the exact text for you?
