1st Linux Attempt -> I'm Discombobulated...

okay, i'm a bit lost here.

1. i have postgresql installed on my system.
2. postgres user exists.
3. i created 3 dbs:

depot_development
depot_test
depot_production

4. i log into postgres user
5. psql -l yields

sh-3.1$ psql -l
            List of databases
       Name        |  Owner   | Encoding
-------------------+----------+----------
 depot_development | postgres | LATIN1
 depot_production  | postgres | LATIN1
 depot_test        | postgres | LATIN1
 postgres          | postgres | LATIN1
 template0         | postgres | LATIN1
 template1         | postgres | LATIN1
(6 rows)

i want to grant all privileges to user "user_name".

as per the tutorial i'm working off of, the mysql
version is...

grant all on depot_development.* to
'user_name'@'localhost'

i was on irc and they said there is no pgsql
equivalent command.  i tried to fire up pgadmin3 to
set grant via the gui, bit i can't login.  postgres
can't read some log and root requests a password file
when logging in as postgres (no password is set).

i'm kinda lost and a helping hand would be
appreciated.
