> It would be good to have a test to check partition pruning on a view like:
> create view t1 partitioned on (ds) as
> select * from
> (
> select key, value, ds from t1_new
> union all
> select key, value, t1_old.ds from t1_old join t1_mapping
> on t1_old.keymap = t1_mapping.keymap and
>    t1_old.ds = t1_mapping.ds
> ) subq;
> While adding the test, I found that the lineage is broken for this.
> Will file a separate issue for that.
