OK, I see; is not that simple eh?, but here is another idea, create a
view, something like:

create view events_v as select distinct on (ref) * from events where date >= now();

and then select limited to 3

select * from events_v order by date limit 3;

This may not do exactly what he wants but is closest solution i can
imagine ;-)
