Indeed, this seems to have very little relation to reality :-(.
I didn't even realize that we had such a description in the SGML docs.
It's obviously not been updated for many years. I'm not sure if the
"continuation" mechanism it describes ever existed at all, but it sure
hasn't been there since the code left Berkeley.

Not that I can think of. The most accurate information seems to be in
src/include/storage/bufpage.h; AFAICT all the comments in that file are
up-to-date. In addition to this it'd be worth pulling out some
description of the "special space" structures used by the various index
access methods.

Go for it.
