I don't see any alternative. If one backend sends a NOTIFY payload that
contains a non-ASCII character, there's a risk that we won't be able to
deliver it to another backend with a client_encoding that can't
represent that character.
Also, just the fact that client_encoding can be changed at pretty much
any time is a potential problem, because it's difficult to know whether
a particular notification was sent using the old client_encoding or the
new one (because it's asynchronous).
