                             List of roles

 postgres  | Superuser, Create role, Create DB, Replication | {}
 tobiasco  | Create DB                                      | {}

But http://www.postgresql.org/docs/9.3/static/sql-createdatabase.html says

"To create a database, you must be a superuser or have the special CREATEDB privilege."

Where to find "privilege"-listing?
