Don't really see the issue. Errors reported by the server are easy to
distinguish by formatting (as long as we don't go out of our way to make
pgbench's errors look like them, which is one reason I do not like the
"HINT" proposal in the bug #12379 thread). Errors reported by libpq
itself might look like they came from pgbench, but I don't exactly see
what's wrong with that. I don't think users much care about the
difference, as long as they can tell server-side errors apart from
client-side errors.
