You can't translate to grouping_id because that's a pseudo function too.

I am trying to understand why {{grouping_id}} would not be the right choice.
Since {{grouping_id}} has as arguments the column references {{i0, i1, i2, i3,
...}}, we are certain that it won't get pushed down, right? That should be
enough.
Sorry about insisting, I'm just trying to avoid creating another pseudo
function {{$Foo}} on my side if it is not really necessary.
