Hi,
Here is a updated version, the main changes are:
1. an shared_detoast_datum.org file which shows the latest desgin and
pending items during discussion.
2. I removed the slot->pre_detoast_attrs totally.
3. handle some pg_detoast_datum_slice use case.
4. Some implementation improvement.

shared detoast datum
See the overall design & alternative design & testing in
shared_detoast_datum.org
In the shared_detoast_datum.org, I added the alternative design part for
the idea of TOAST cache.
