Allow user to create tables

Hello,

I just created a database and granted all rights to the tables I created to
an additional user.  I observed that this user does not have the right to
create additional tables.  Which right do I have to grant to this user
to give him full access (including creating new objects like tables,
sequences, etc. ) to this additional user?

I'm using PostgreSQL 7.2.1.

Kind regards

          Andreas.
