I reported an incorrect description for auto-analyze in our documentation. http://archives.postgresql.org/pgsql-hackers/2007-06/msg00000.php Here is a documentation fix for it.
There are the same mistakes in 8.1 and 8.2, not only in HEAD. It had been true in contrib/pg_autovacuum at 8.0, but we changed the behavior at the integration of autovacuum.
