I'm fairly sure this won't work in the case of compound keys - I think we'll need to do a bit more complex dance where we do things like (assuming our last result was `{key1: 'foo', key2: 'bar'}`):

```SQL
WHERE key1 = 'foo' && key2 > bar # this comes up empty
WHERE TOKEN(key1) > TOKEN('foo')
```

But I'm OK with it for now.
