That discussion has approximately nothing to do with the
much-more-invasive change that Itagaki-san is suggesting.

In particular I think an automatic change of client_encoding isn't
particularly a good idea --- wouldn't you have to change it back later,
and is there any possibility of creating a security issue from such
behavior?  Remember that client_encoding *IS* tied to security issues
such as backslash escape handling.
