It's not easy to see what exactly changed between this and that version, on
a specific page on documentation. As an example I got this page but you'll
see this problem anywhere on docs.
https://www.postgresql.org/docs/16/functions-json.html
and
https://www.postgresql.org/docs/devel/functions-json.html
There are lots of new functions and better explanations of old features.
Then my question is, how to know all pages which were changed and what
exactly was changed on those pages ?
