They are in a separate list “Methods”. This approach was used for other databases long before generated columns were implemented in PostgreSQL.
====================
It has to do with the syntax of generated and that you can generate data in different ways. Calling those ways “methods” seems reasonable.
It's hard to argue with that. However, it is not quite clear to me, what origin are we talking about? I have worked with MS products and currently with PostgreSQL and have not encountered this interpretation.
“Origin”? The documentation, and my internalizing of it based on my personal experiences.
Anyway, I did my best given the unclear (to me at least) and limited information you provided, and the fact I don’t really understand the question.
