When mysqldump is executed for only one database, it runs smoothly. If it's executed for more than one database, it throws a warning on each additional schema.
I suppose these warnings are just as harmless as the previous ones, but it would be nice to fix/suppress them anyway.

If it's executed with --all-databases option, it throws some more warnings (even although there are only these two databases, 'mysql' and 'test':
