I've posted some preliminary design ideas at
https://www.postgresql.org/message-id/15193.1548028093@sss.pgh.pa.us
and

While there's a nontrivial amount of work needed to make that happen,
I think it's doable, and it would lead to a significantly better
solution than proceeding along the inlining path could do. My
current feeling, therefore, is that we should reject this patch
(or at least stick it in the deep freeze) and go work on that plan.
