Thanks for drafting that up.

I think it would be more accurate to say "inner-side of nested loop joins".

I'd say we already had that feature with TID Scan. Maybe it would be
better to write:

"Allow efficient heap scanning on ranges of tids (Edmund Horner, David Rowley)"

I think it is worth mentioning "I/O" before "performance". This
change won't really help cases if all the table's pages are already in
shared buffers.
