-- This file contains part of the changes required to upgrade from Revision 1 to Revision 2 (DB version 6 and revision 1)
-- It actually contains only the changes that:
   -- can not be executed with an idempotent statement in SQL
   -- or would polute the PrepareIndex.sql
-- This file is executed only if the current schema is in revision 1 and it is executed 
-- before PrepareIndex.sql that is idempotent.


-- add unique constraints if they do not exists
