You may want to review the fixes between 8.1.8 and the latest 8.1
bug fix release, which is 8.1.20:

http://www.postgresql.org/docs/8.1/static/release.html

Perhaps one of these fixes would help.  I'd certainly recommend
applying the bug-fix update and seeing if the problem is still
there.

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.
