Hi,
If you want to send me script(s) to alter tables and add contstraints as appropriate I will add them in as an upgrade script. Please test after making the changes on your system and let me know if adding these constraints cause any errors like if you try to delete a page and it has child objects like content on it. It should not cause errors but please test some to make sure so that if it does I can fix them.
Over time as a continue making the changes to guids I may have to drop some of these contraints and add different ones.
Thanks,
Joe
