Older versions of tools are not guaranteed to be compatible with newer versions
of the server. You should use the dump/restore tools of the version you are
targeting. For other clients like psql it's usually fine to use the latest
version against older servers.
If you have a mix of server versions installed you need to put in the work of
ensuring you are using the right version of the clients as well.
