Is this a known problem? Is there a work-around?
create table t (c char, i int);
insert into t values ('a', 1);
insert into t values ('a', 1);
insert into t values ('a', 2);
insert into t values ('b', 2);
select distinct on (c, i) c, count(i) from t group by c;
ERROR: Attribute t.i must be GROUPed or used in an aggregate function
