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 ...)
