Revoke for a new role

Hi folks,

I'm new in this mailing list.

I need to create a role (Postgres user) that cannot drop or create table, but can create TEMP tables. This role must do I, U and D normally.

I have read some docs over the web and discovered that option to revoke "create table" doesn't exist.

Can someone give me a light?!

Thnks
