Обсуждение: libpq PGresult object and encoding

libpq has a PQclientEncoding() function that takes a connection object. 

However, the client encoding is, in some cases, a property of the result
object. For instance, if your client_encoding changes, but you keep the
result object around, you have no way to determine later what encoding
the results are in.

The result object already saves the client_encoding. Should an accessor
be provided?

That'd certainly save libpqxx the trouble of lugging a copy around.
