Agreed.

It's still not clear to ne that we should make pg_getaddr_info() mimic the API
of getaddrinfo since it's not a thin wrapper over getaddrinfo.  The alternative
option would be to return EAI_FAIL on a null hint and force the caller to
provide an AF_UNSPEC if that is what is indeed asked for.
