Help with Vacuum Failure - Mailing list pgsql-hackers

Hello, I'm having a problem vacuum a table and I didn't see an answer using
the fts engine.

I have two questions:

1) Is this a big problem, can it be fixed, do I have to dump / restore this
table?
2) I found this problem from my nightly cron driven vacuum -a -z.  When it
hits this error the entire vacuumdb process stops immediately thus skipping
any remaining databases.  Should it do this?  Or should it continue on and
vacuum the other databases?

Here is the error:

cms_beau=# vacuum hits;  (It works without the analyze phase of backup.)
