postgresql-7.1beta1 initdb error

Hi,

I'm working with postgresql-7.1beta1 on Solaris 8, and I get this error when
running initdb as the "postgres" user:

-----
$ initdb -D /opt/pgsql/data -W
This database system will be initialized with username "postgres".
This user will own all the data files and must also own the server process.

To whom should I report the error? And does anyone have a suggestion? I'm
new to PostgreSQL, so it's possible I've done something obviously wrong.

Thanks!
