Ron's point is that you are currently at Postgres 14.6 and there are
approximately 4 years of bug fixes to the current stable 14.22 version
as seen here:

https://www.postgresql.org/docs/14/release.html

It would be good idea to bring the 14 instance to as an up to date state
as possible before moving on to latest major version(18), which in
itself is a jump of 4 major versions.

As to the major to major upgrade I would suggest reading:

https://clusterlabs.org/projects/pacemaker/doc/3.0/Pacemaker_Administration/html/

and

https://www.postgresql.org/docs/18/pgupgrade.html
