Creating such a chapter in "VII. Internals" will increase the existing chapter numbers 50 - 71, which may lead to some confusion. On the other hand the content can possibly be applied to all supported PG versions at the same time, which will lead to a consistent behavior. Extending one of the existing chapters won't work because all of them handle their own topic, eg.: "50. Overview of PostgreSQL Internals" (misleading title?) focuses on the handling of SQL statements from parsing to execution.
What are your thoughts?
v14 has already added a new chapter, installation from binaries. It was not back-patched. To my knowledge no one brought up these points - numbers changing or back-patching the new material. I don't see that this enhancement needs to be treated any differently.
