Not sure I am following your point here. Taking your patch, it is
possible to trigger the version of get_raw_page() <= 1.8 just with
something like the following:
create extension pageinspect version "1.8";
select get_raw_page('pg_class', 0);
There are no in-core regression tests that check the compatibility of
extensions with older versions, but it is technically possible to do
so.
