I imagine this could be sped up a lot using tricks like this one from the SQLite documentation: https://sqlite.org/pragma.html#pragfunc

```sql
SELECT DISTINCT m.name || '.' || ii.name AS 'indexed-columns'
  FROM sqlite_schema AS m,
       pragma_index_list(m.name) AS il,
       pragma_index_info(il.name) AS ii
 WHERE m.type='table'
 ORDER BY 1;
```
