This is only true for server encodings. In a client library I think
you lose on this and do have to deal with it. I'm not sure what client
encodings we do support that aren't ascii-supersets though, it's
possible none of them generate quote characters this way.
I'm a bit surprised libpqxx isn't using binary mode internally though.
This would at least avoid the problems with encoding. However I'm not
sure things like the array binary format are really stable and
portable enough to really use from a client library. Some datatypes
might be dependent on the server ABI (floats -- I'm looking at you) so
that might make it difficult or impossible.
