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 Shridhar -- Live long and prosper. -- Spock, "Amok Time", stardate 3372.7
