Pushed with minor adjustments. My first experiments with this say that
we should have done this long ago:

I agree that using INT_MAX is more consistent with the code elsewhere in
guc.c, and more correct given that we declare the variable in question
as int not int32. But you need to include <limits.h> to use INT_MAX ...

As of 4c56f3269a84a81461cc53941e0eee02fc920ab6 I'm still getting it in one of my queries:
ORDER/GROUP BY expression not found in targetlist
Am I missing something?
I could dig into this further to reproduce if necessary.
