Hm... in my point of view it's a bug, but not necessarily a PG bug. My
desired result is the correct translated output in different languages.
Now i know that this is not possible, because i have to use the correct
lc_ctype for the entire database, which can't be changed after the
database-creation.
The only work-around seems to be to handle the translation myself.
That's very ugly and makes the use of TMMonth pointless, if you have to
take care of the result-output before you use the database.
Thanks to all for your time and help,
