autovacuum template0

I've got a pg 8.1.1 server running autovacuum, and it started attempting
to vacuum template0.

2006-06-22 15:00:50 EDT LOG:  autovacuum: processing database "template0"
2006-06-22 15:00:50 EDT ERROR:  could not access status of transaction
3242180415
2006-06-22 15:00:50 EDT DETAIL:  could not open file "pg_clog/0C13": No
such file or directory

I found a thread about the same problem at
http://archives.postgresql.org/pgsql-hackers/2006-03/msg01294.php, but
it doesn't say if the resolution works.  Does anyone have experience
with this?  I'm at a loss as to what I should do.

Thanks,
