…other updatable views
> Only mark view as updatable if rows cannot overlap with other updatable views

> Issue Type: Sub-task
> Reporter: James R. Taylor

> Priority: Major
>
> We'll run into issues if updatable sibling views overlap with each other. For
> example, say you have the following hierarchy:
> T (A, B, C)
> V1 (D, E) FROM T WHERE A = 1
> V2 (F, G) FROM T WHERE A = 1 and B = 2
> In this case, there's no way to update both V1 and v2 columns. Secondary
> indexes wouldn't work either, if you had one on each V1 & V2.
> We should restrict updatable views to
> - views that filter on PK column(s)
> - sibling views filter on same set of PK column(s)
