First of all, it would help you and most of the readers on this list, if
you have the error messages in english. There is a german mailinglist
too, if you want to ask in german.

vacuum all databases, add the VERBOSE option to see, what actually
happens.

Are you using the database 'postgres' at all? And are you sure, that
you include all databases? Any error messages in the vacuum output?
Oh, and by the way: why do you have autovacuum and a manual vacuum run
every night plus the vacuum run with verbose?
