I know I sent an email earlier this month saying we shouldn't
over-document the backend hooks because the code could drift away from
the README content:

	https://www.postgresql.org/message-id/20210309172049.GD26575%40momjian.us
	
	Agreed.  If you document the hooks too much, it allows them to drift
	away from matching the code, which makes the hook documentation actually
	worse than having no hook documentation at all.

However, for this doc patch, the content seem to be more strategic, so
less likely to change, and hard to figure out from the code directly.
Therefore, I think this would be a useful addition to the docs.
