Actually, it might be possible to use the PITR system to restore up to
just before the error (the transaction-id above might be a good start
point).

You'll want to move your WAL files to a different directory so it looks
like they've been copied from another machine. See this section of the
manuals for details of how to set up the recovery. Take your time
reading it thoroughly.
http://www.postgresql.org/docs/8.0/static/backup-online.html

IMPORTANT - make sure you have a backup copy of the entire data
directory before trying this.

A warning - I've not tried this particular idea out, but as long as you
can partially replay the first WAL file, I don't see why it shouldn't work.
