The CommonSQL API as published and implemented by Lispworks. This is
the API which CLSQL strives to maintain backward compatibility. CLSQL
does maintain some extensions to the CommonSQL API which do not break
backward compatibility.

As for the behavior of update-records-from-instance, yes, it could be
extended. Perhaps a better solution would be to add a function to
explicity change the view-database of an object. Of course, that's
rather trivial [untested]:
  (defun (setf db-object-database) (db obj)
     (setf (slot-value obj 'clsql-sys::view-database) db))

However, I've not thought through whether there are any potential
issues with changing the view-database slot of a db-object which
already has a non-null value of in the view-database slot.
