For AIX 5.1, if I compile it as is with the 4 value then it SEGVs but
it is fine if I set it to zero. They have the define in the header but
not in the manual page. My guess is that at least in 5.1 it is an
incomplete implementation. The header more accurately reflects the RFC
then the actual implementation.
I do agree though it isn't postgres's fault and it sounds like it is
fixed in AIX 5.3 anyway.
Thanks,
