> Try something like the following query:
> {code}
> select pod, count(*) as orgs from organization group by pod order by pod desc;
> {code}
> versus this one:
> {code}
> select pod, count(*) as orgs from organization group by pod order by pod asc;
> {code}
> There may be some missing logic in how we setup the client-side order by in this case.
