FreeBSD 7.1 Release, Postgres v8.3.7 and confusion on a howto

All,

I'm following this howto:
     http://www.howtoforge.com/virtual_hosting_vsftpd_postgresql_freebsd

and can't get past setting up the database.

I've installed postgres, and it starts successfully after an initdb
[1], but I come to a full stop after the following commands:

     it-kbuff-fbsd# su - pgsql
     $ psql system
     psql: FATAL:  database "system" does not exist

Huh? Is it a problem with the howto, or a mismatch between the howto
and version of postgres I'm using, or am I performing a newb stunt?

Any help appreciated.

Thanks,

Kurt

You can change this by editing pg_hba.conf or using the -A option the
next time you run initdb.

Success. You can now start the database server using:

    /usr/local/bin/postgres -D /usr/local/pgsql/data
or
    /usr/local/bin/pg_ctl -D /usr/local/pgsql/data -l logfile start
