There is no way to deny a superuser access to a schema. Don't use superusers for anything else than administration. One way I can think of to force users to create tables with schema qualified names is to set "search_path" to "pg_catalog". Then only the temporary schema and the catalog schema can be used without qualification. Every user can use "SET search_path = ..." to change the setting, but a script that does that documents at least where the table *might* be created. Yours, Laurenz Albe
