If you mean can one session identify the client_encoding of another
session, no; that information isn't exposed anyplace. Within a session,
you can of course use "show client_encoding" or various equivalent
syntaxes.
Note that when you have encoding problems, as often as not the issue
is that the data the client is sending isn't really in the encoding
its client_encoding setting claims. So even if you could find that
out remotely, it probably wouldn't help localize the issue very well.
