Connection errors are handled by the client, which knows the client encoding.
If the setting of the client encoding would be one of the first things to be
done on the server side, you would only have a handful of possible error
conditions left (e.g., setlocale failed, out of memory). You could choose to
report those in plain ASCII or send a special error code that the client can
resolve. Although I guess no one could fault us if "could not set language"
is reported not translated. ;-)

Ultimately yes. But we currently handle the client encoding quite late in the
startup sequence so that many connection startup failure messages that are of
interest to normal users would likely be affected. So moving the client
encoding handling to the earliest possible phase would still be desirable.
