I had intended to address with policies what is addressed through permissions with 7d8db3e, but the coverage for INSERT+RETURNING was only done when ON CONFLICT was in use. I've fixed that by applying the SELECT policies as WCOs for both the INSERT and UPDATE RETURNING cases. This matches the permissions system, where we require SELECT rights on the table for an INSERT RETURNING query. Thanks! Stephen
