Is a system view the right interface?  For example, in pgbouncer we just 
added it to the version output:

$ pgbouncer --version
PgBouncer 1.18.0
libevent 2.1.12-stable
adns: c-ares 1.19.0
tls: OpenSSL 3.3.2 3 Sep 2024

That way, you can get this information without having to start a server 
instance.  (Maybe you can't start a server instance because it just 
crashed because of some library version issue ...)
