Well at first I thought that you could create an in-memory tablespace. But it doesn't seem like its a good idea though, http://stackoverflow.com/questions/7872693/running-postgresql-in-memory-only http://stackoverflow.com/questions/7872693/running-postgresq... So I guess if you need in-memory data, SQLite or Redis are better options.
