problem with localization

Hi,

I'm new to pgsql and have run into the first problem. I can't persuade pgsql
to localize (German). As far as I got the manual, pgsql should recognize the
users' environment variable like LC_NUMERIC etc. and adjust the output
accordingly. Unfortunately the output (using psql) is always the same: date
in iso format and numbers with decimal point instead of the required comma.
Pgsql has been compiled with locale enabled and I have made sure that the
environment variables are set correctly (de_DE@euro, I also tried de_DE).
What did I forget?

Thanks
Carsten
