The next byte of the buffer is tested against ' ' before its availability is checked. Hmm, yeah. The probability of a failure is very low of course, but still it'd be better if the sample code didn't have bugs like this. > You will find attached a simple patch that fixes the bug. Will apply, thank you. regards, tom lane
