Granting a user account permission to create databases in PostgreSQL

How do I give a user account in PostgreSQL the ability to create and drop databases? Is there a way to do this with GRANT?

It's done with ALTER USER username CREATEDB;

See ALTER USER in the doc.

To drop a database, either you're superuser (which can be granted with ALTER USER too) or you must own the database.
