   I think my confusion comes from the fact that PK means unique and not null 
and that having null in any column in the tuple we upsert by, means that tuple 
matches nothing from the SQL perspective. It feels easier to assume columns we 
use in equality deletes are not nullable. I agree about the downside of not 
being able to use optional columns added later as identity columns but I am not 
sure how important that is. We can probably cover that use case with default 
values that LinkedIn is working on.
