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
 
I am working on preparing a patch to fix this issue.
 
 
Am I missing something?
 

No, the fix is still not committed.
 
Ah, I thought Tom pushed a fix, but it apparently was another fix.
 
Thanks for fixing.
