Maybe I'm misundertanding your diagram - did you mean this ?

I think you're considering the issue where pg_dump support is dropped
for very old versions - that'd be something that's like ~10 years old.
For example if someone has a pg9.1 server, and then installs pg15
clients, which dropped support for v9.1.
Wouldn't that be handled here for pg_dump, the same as for psql ?
if ($version and $version < 9.2) { # psql 15 only supports PG 9.2+
