It is possible to check just once at the end, using the PQExpBufferBroken
API, and I believe that libpq for instance is fairly careful about that.
I agree that programs that just need to print something and exit could
perhaps ask pqexpbuffer.c to handle that for them. (But initdb still
doesn't fall in that category, because of its very nontrivial atexit
handler :-(.)

Perhaps. You wouldn't get any translation --- but then, gettext is
probably going to fail anyway under such conditions.
