I'd like to propose the ability to create temporary schemas.
Unlike temporary tables, this feature would enable developers to create a temporary schema once and execute CREATE TABLE statements without the TEMPORARY parameter.
I think you can use "pg_temp" for this - it's an alias to the current session's temporary schema. If you set the current schema with "SET search_path TO pg_temp", all tables, views, functions and so on will be created in a temporary schema.
