User creation of DB

Hi all,

I've just installed Postgresql, I've created a db using user
postgres, but how can I give a user permissions to create one
too...
Since, when I do:
pdestroy@localhost:~$ createdb test
psql: FATAL 1:  user "pdestroy" does not exist
createdb: database creation failed

Any ideas?

Best regards,
