That article is fractally wrong, and that starts right in the first
sentence. See
https://www.postgresql.org/docs/15/functions-info.html#FUNCTIONS-PG-SNAPSHOT
(not getting into detail discussions, but still).
Anyhow, the article does not discuss requirements and limitations of
pg_rewind, and promotes unsafe practices. After reading this article,
I'd be more than careful with anything else published by that source.

It's not an official feature. There's a limited amount of thing you can
get away with when breaking and rewinding replication, but the guarantees
on those are rather weak.
