This would either mean to rewrite SQL query in the driver or to modify
the application. rdb$db_key does not belong to the application data
model, has no meaning there and, I believe, should not be visible by
the application in general. Rewriting SQL in a driver is not what I
want. I believe that driver should be dumb and act as a simple
interface converter, not to do work that belongs to the database server.
