Problem with Upper/Lower Function

I fond a problem at the RC1 of PostgreSQL (W32 - Version)

When you use the UPPER or LOWER function with German letters (ä,ö,ü) this
letters stay in lower/upper case.
You can reproduce this error with this simple examples:

select upper('ü');
select upper('Tüte');

Test
ID | sText
-------------------
1 | TÜTE
2 | EIMER

select * from Test where sText = upper('tüte');

I can reproduce this problem in several computers.

Mit freundlichen Gruessen / with best regards
