Comment (by Mariusz Felisiak):
Just want to add that it also crashes without `ARRAY`, e.g. for a queryset
from [https://code.djangoproject.com/ticket/34255#comment:1 comment:1]:
{{{#!sql
SELECT
JSONB_BUILD_OBJECT(
(%s)::text,
EXTRACT(YEAR FROM "ticket_34255_point"."start_at" AT TIME ZONE
%s),
(%s)::text,
AVG("ticket_34255_point"."value")
) AS "json"
FROM "ticket_34255_point"
GROUP BY
EXTRACT(YEAR FROM "ticket_34255_point"."start_at" AT TIME ZONE %s)
}}}
{{{
psycopg.errors.GroupingError: column "ticket_34255_point.start_at" must
appear in the GROUP BY clause or be used in an aggregate function
}}}
