Unlike with other databases, a PostgreSQL database cannot be created without a user. You must stick to the following sequence:
1. Create a PostgreSQL user.
2. Create a database.
Note: The first user in the list of users is the owner of a database, however the database can be used by others who obtain permissions from the owner.
To create a PostgreSQL database user, do the following:
1. Select PGSQL in the Databases menu and Add PostgreSQL user form automatically appears.
2. Fill the Add PostgreSQL user form on the PostgreSQL Users page.
3. Agree to additional charges.
