What do you mean by "0 (?)"?  There shouldn't be any entries in
pg_attribute with attnum zero.  The row looks pretty completely bogus
otherwise, so I wonder if it's something you put in manually in a
misguided effort to fix whatever the real problem is.

As Kevin noted, 8.1.8 is really ancient, so you ought to update to
8.1.something-recent before you spend much more time on this.
