Maybe in an ideal world that'd be the case, but psql has always just
depended on PQerrorMessage(). I don't think this patch should be
tasked with changing that. I'm not even sure that doing so would be
a good idea: I think the idea there is that whatever we believe is a
nice error-reporting option for psql ought to be easily available to
other libpq clients too.
(Note: I haven't read the patch and don't mean to be saying that it's
necessarily OK. But I'm fine with the idea that something like this
involves touching libpq more than psql.)
