That seems like a far easier, cleaner, and more robust fix than this.
Moreover I don't believe that this approach works either, as the result
of strerror() is not guaranteed still usable after another strerror call
(ie, it can use a static buffer repeatedly), so you'd still have the
problem if libpq_gettext invokes strerror. I suppose that a really
robust solution would involve libpq_gettext saving errno, restoring
errno, and invoking strerror() again ...
