Comment (by Simon Charette):
Right, it doesn't need `ARRAY` to be present to reproduce the crash but
the reason why we can't simply augment the select clause with `year` in
order to `GROUP BY 1` (or `GROUP BY year`) is that it would return a row
with two columns and differ from what the user is asking for when doing an
explicit `values("json")`.
