- Wrong FLAG values transmitted to created table by the AS SELECT table:

  It is not enough to ignore the flags while populating the table. They have
  to be removed from the definition in pre_create. The issue is to pass the
  info from the selected table handler to the created table handler.
  It is done via the only common item between them: the GLOBAL structure.
