I'm hesitant to do that. We can afford to insist that our own header files be inclusion-order-independent, because we have the ability to fix any problems that might arise. We have no ability to do something about it if the system headers on $random_platform have inclusion order dependencies. (In fact, I'm fairly sure there are already places in plperl and plpython where we know we have to be careful about inclusion order around those languages' headers.) So I would tread pretty carefully around making changes of this type, especially in long-established code. I have no reason to think that the committed patch will cause any problems, but I do think it's mostly asking for trouble. regards, tom lane
