And to answer your second question: I am not sure. The current behavior of
the code is that the CQD is required if doing CREATE TABLE LIKE from sqlci. I
think one could make a case for changing that behavior. On the other hand, one
might want to prevent casual propagation of nullable primary keys. Which would
be an argument for always requiring the CQD. I don't feel strongly either way.
