locale of the database should be de_DE.utf8 (if the database is with
encoding UNICODE) or de_DE in case the encoding is LATIN1.

check it with

show lc_ctype
show database_encoding

You cannot officially change the locale of the database so
theoretically you can buckup and restore the database to the correctly
initialized database.

I have managed to chenge the control file and reindex the database and
do not see any problems yet.
