I thought I understood your idea, but now you lost me again. I thought what you want is that the older heap tuple has a pointer to the newer one. Which it already has, it's called t_ctid.

Can you try to explain more carefully how the whole thing would work? What would an index tuple point to? What pointers would a heap tuple have? What would an index scan do to find the row version it's interested in? What exactly would an update do?
