Thanks. I think I get the point - is it dngettext doing things
differently for different languages?

#define EVALUATE_MESSAGE_PLURAL(domain, targetfield, appendval)  \
    { \
        const char     *fmt; \
        StringInfoData  buf; \
        /* Internationalize the error format string */ \
        if (!in_error_recursion_trouble()) \
            fmt = dngettext((domain), fmt_singular, fmt_plural, n); \
        else \
            fmt = (n == 1 ? fmt_singular : fmt_plural); \
        initStringInfo(&buf); \
