Yes, new path type, new plan type, probably a new access method if
you want to keep things clean in the executor, cost-estimation routines
in the planner, etc. etc.

Looks like a lot of work, and a lot of added code bulk that will
have to be maintained.  I haven't figured out why you think it's
worth it... tids are so transient that I don't see much need for
finding tuples by them...
