problem logging on with new everyday user

I am a newbie and just installed PostgreSQL 8.4 on Ubuntu.  I can get in with my postgres user but when I create an "everyday" user, I can't login with it:

johnp(at)sussancws0114:~/downloads$ /opt/PostgreSQL/8.4/bin/psql   -U postgres
Password for user postgres: 
psql (8.4.14)
Type "help" for help.

Cannot read termcap database;
using dumb terminal settings.
postgres=# drop user johnp;
DROP ROLE
postgres=# create user bruno password 'hello';
CREATE ROLE
postgres=# \du
            List of roles
 Role name | Attributes  | Member of 
-----------+-------------+-----------
 bruno     |             | {}
 postgres  | Superuser   | {}
           : Create role   
           : Create DB     

postgres=# \q
johnp(at)sussancws0114:~/downloads$ /opt/PostgreSQL/8.4/bin/psql   -U bruno
Password for user bruno: 
psql: FATAL:  database "bruno" does not exist
johnp(at)sussancws0114:~/downloads$ 

What am I doing wrong?
