Maybe something like that: CREATE TABLESPACE spcname LOCATION '/foo/bar' WITH (only_temp_relations = true); Have in mind you must take care if you use ALTER TABLESPACE spcname SET (...) to guarantee that exists only temp objects stored in the target tablespace, and if exists a regular object you must throw an exception.
