Thanks for working on the draft. Here're some comments for it:

1) Improve performance of pgstattuple by using streaming reads

There are two related commits that improve the performance of
pgstattuple. The current hyperlink references [1]; would it make sense
to include [2] too?

[1] https://git.postgresql.org/gitweb/?p=postgresql.git;a=commitdiff;h=213f0079b
[2] https://git.postgresql.org/gitweb/?p=postgresql.git;a=commit;h=ae58189a4d523f0156ebe30f4534180555669e88


2) Additionally, would this[3] be something worth mentioning in the
General Performance section? The improvement looks fairly big.

[3] https://git.postgresql.org/gitweb/?p=postgresql.git;a=commit;h=6c228755add8f0714677440d53a160f9ed332902


3) Allow standbys to wait for LSN values to be replayed via WAIT FOR
As for this feature, the follow-up commit[4] extends the WAIT FOR
command to support waiting for flush and write operations. Is it
helpful for users to be aware of these use cases as well?

[4] https://git.postgresql.org/gitweb/?p=postgresql.git;a=commit;h=49a181b5d634340fcfb7c762c387c03f6405367e

Thanks!
