Обсуждение: upper and lower doesn't work with german umlaut?

hello, what is wrong?

postgresql 7.1.3
suse linux 7.1

configure postgresql:
./configure --prefix=$DIR_DEST --exec-prefix=$DIR_DEST
        --enable-local --enable-multibyte
        --enable-odbc --enable-syslog --with-java

init database:
$DIR_DEST/bin/initdb --pgdata=$DIR_DB01 --encoding=LATIN1

check LANG-variable:
postgres@server:/app/pgsql/bin > echo $LANG
de_DE

and that's the result:

    my_db=# select lower('ÄäÜüÖöß');
      lower
    ---------
     ÄäÜüÖöß
    (1 row)

uppercase umlauts are not converted.


thanks
frank

Did you run initdb with the correct LANG environment?

To check, run contrib/pg_controldata and see what it says about
LC_COLLATE and LC_CTYPE.
