Install and Set up Postgresql DB in Ubuntu 9.04

Open a terminal window, and type the following command to install it:

rosh@rosh-desktop:~$ sudo apt-get install postgresql

Make a dicrectory to keep db sources (You don't have to have same path and directory name as I have):

rosh@rosh-desktop:~$ mkdir /usr/local/pgsql/data

Change the owner of directory:

rosh@rosh-desktop:~$ chown postgres /usr/local/pgsql/data

Also, you can change both the owner and the group information of 'data' directory if you want or need:

rosh@rosh-desktop:~$ chown postgres:postgres /usr/local/pgsql/data

Switch user to postgres:

rosh@rosh-desktop:~$ su - postgres

Initialize the DB server:

postgres@rosh-desktop:~$ /usr/lib/postgresql/8.3/bin/initdb -D /usr/local/pgsql/data

Create new DB (You can pick any db name instead of using 'db'):

postgres@rosh-desktop:~$ /usr/lib/postgresql/8.3/bin/createdb db

Create new user (You can pick any user name instead of using 'user'):

postgres@rosh-desktop:~$ createuser -U postgres -d -P user

Exit from the DB and run it::

postgres@rosh-desktop:~$ exit
rosh@rosh-desktop:~$psql -s db

Done!

Here is the options I used above,

psql

-s(--single-step): Run in single-step mode. That means the user is prompted before each command is sent to the server, with the option to cancel execution as well. Use this to debug scripts.

createuser

-d(--createdb): The new user will be allowed to create databases.
-P(--pwprompt): If given, createuser will issue a prompt for the password of the new user. This is not necessary if you do not plan on using password authentication.
-U(--username): User name to connect as (not the user name to create).

Then just make sure you deselect the other JREs and only have this one selected.
