The error message seems pretty clear to me:
ERROR: in an aggregate with DISTINCT,
This...on 9.3
SELECT array_agg(
distinct case when v % 2 = 0 then 'odd' else 'even' end
order by case when v % 2 = 0 then 1 else 2 end
)
FROM (VALUES (1), (2), (3)) val (v)
I'm not particularly irked at this though I was hoping to fix a somewhat
complex query of mine by simply adding a "DISTINCT"
