Now you will create a database where the Atlassian JIRA application will store its data, and a user role that JIRA will use to connect to the database. We are assuming that you have already created your PostgreSQL database server in a previous step.
We are using pgAdmin III (version 8.4.x) the administration user interface supplied with PostgreSQL. If you used the one-click installer when installing PostgreSQL, pgAdmin III will be already installed on your computer.
pgAdmin III instructions
Start pgAdmin III.
Right-click (or double-click) the database server name and log in using the password that you specified for the 'postgres' super user.
Add a new login role called 'jirauser':
Right-click Login Roles and select New Login Role.
Enter the role Role name: jirauser
Enter a Password and enter it again to confirm it.
Click the Role privileges tab.
Select Can create database objects.
Select Can create roles.
Click OK to create the user.
Add a new database called 'jira':
Right-click Databases and select New Database.
Enter the database Name: jira
Select the Owner: jirauser
Click OK to create the database.

Assuming that you are using the default installation directory of /opt/PostgreSQL/8.4/bin/, enter the following commands:
