Well, this is not related to postgresql exactly but to summerise the problem,
with libc patch PHCO_19090 or compatible upwards, on HP-UX11, isspace does not
work correctly if input value is >127. Can cause lot of problem for an external
app. It works fine with unsigned char
Does not make a difference from postgrersql point of view but would break non-
english locale if they want to use this fix under some situation.
But I agree, unless somebody reports it, no point fixing it and we know the fix
anyway..
Bye
