No, if you set it to plain it won't be stored externally. But setting to
plain actually increases the size of data (no short varlenas anymore),
so its not really a sensible choice imo. It also doesn't prevent
creation of a toast table - it just won't get used.
If you only create columns that are too short for toast (like
varchar(12) or so), the toast table won't get created.
