Depends on the impact the restriction imposes. If 
stability/scalability/functionality or so is affected, this sounds not 
tolerable. If it's about not saving two bytes that have been spoiled for 
ages before, or keeping a backward compatibility type, it appears 
feasible to me.
Changing on-disk structures at the start of the 8.2 dev cycle is a 
guarantee that nobody will implement pg_upgrade for 8.2.

Andreas
