Relation "reviews" with OID 16856 no longer exists

I recently dropped and recreated the table reviews and the view review_status
and now I get this:

SELECT review_num from review_status WHERE date_closed IS NULL
Relation "reviews" with OID 16856 no longer exists

I tried running a vacuumdb -f on the database and restarted it and I still get
this.

How do I fix this?

Cordially,
Scott
