Does this make sense? In essence, make the relations work like PL/pgSQL 
variables do. If you squint a little, the new/old relation is a variable from 
the function's point of view, and a parameter from the planner/executor's point 
of view. It's just a variable/parameter that holds a set of tuples, instead of 
a single Datum.

Something to keep in mind is that users will definitely think about NEW/OLD as 
tables. I suspect that it won't be long after release before someone asks why 
they can't create an index on it. :)
