Thank you, I would have never guessed.
$ pg_dump -V -h x
pg_dump (PostgreSQL) 17.4 (Ubuntu 17.4-1.pgdg22.04+2)
$ pg_dump -V
pg_dump (PostgreSQL) 12.20 (Ubuntu 12.20-0ubuntu0.20.04.1)
(facepalm)
I was using the latter checking what pg_dump version was actually being used.
Wasn't aware of this pg_wrapper business.

Yeah, this wouldn't have helped a bit.

If you do something like:
ls -al /usr/bin/pg_dump
you will find pg_dump is a sym link to:
/usr/share/postgresql-common/pg_wrapper
which is a Perl script that does the selection.
The same holds for the other Postgres commands in /usr/bin/.
FYI, psql will always resolve to latest version installed, --cluster
will have no affect on it.
