I recommend keeping pg_isblank but redefining it along the lines of

        bool
        pg_isblank(unsigned char c)
        {
            return (!IS_HIGHBIT_SET(c) && isblank(c));
        }

to ensure the previous treatment of non-ASCII data.
(It could be made static in hba.c, perhaps)

Ok, done that way.
