As far as complexity goes, would it be easier if we treated the UPDATE of a primary key column as a DELETE plus an INSERT? There's not really a logical reason why updating a primary key has meaning, so allowing an ExecPlanQual to follow the chain across primary key values doesn't seem valid to me. That would make all primary keys IMMUTABLE to updates.
