Adding a user to a database
Once you have created a user, you can add that user to the required PostgreSQL database.
To add a user to a database:
Click on the PostgreSQL link in the navigation area.
Click on the + Add Access next to the required user.
Click on the required database from the Database drop-down list.
Click on one of the options in the Access Type area to set the user's permission level for this database.
Enter the database host name in the Hostname field. For most situations you can leave this as the default setting.
Click on the Add Access button.
