Yeah. I sort of thought maybe one of the files in src/include/libpq would be the right place, but it doesn't look like it.
If we at least created the defines and replaced occurrences with the same, then we can litigate where to put them later.
I think I'd prefer this in a different patch, but I'd be willing to take a run at it.
