Um. libpq has its own error messages that it can generate --- the most
obvious ones being those about "failed to connect to postmaster"
and "lost connection to backend". How is it supposed to get a localized
equivalent message from the server in cases like that?
Bear in mind that libpq may be executing on a remote machine, so
"have it read the error message file directly" is not a usable answer.
