Maybe, we should format it to string before for localization messages,
like the following code snippet comes from pg_backup_tar.c.
However, I do not think it is a good way.
snprintf(buf1, sizeof(buf1), INT64_FORMAT, (int64) len);
snprintf(buf2, sizeof(buf2), INT64_FORMAT, (int64) th->fileLen);
fatal("actual file length (%s) does not match expected (%s)",
buf1, buf2);
