I'm not sure why you'd want it. You can't do anything with automatic indexes anyway: they can't be dropped. The only indexes you can DROP are the ones which have their own listing in the sqlite_master table. If you're trying to figure out the TABLE's contraints, you can't use indexes anyway. You have to do it by looking at the column definition and the foreign keys, and these have their own entries in sqlite_master.
