It is unclear to me how you got from your input data to yo= ur expected output. If you are "tryin= g to count() overlapping entries" then it would seem to me that you wo= uld only have only one value for the count. Either a range overlaps or it d= oes not.

Oh, sorry, the count was in wrong order.

Let me explain,
insert into event(name=
, start_time, end_time)
    values=
('a', '2015-12-20', =
NULL)
        , ('a', '2015-12-20=
', '2015-1=
2-31')
        , ('a', '2015-12-25=

2-04')
        , ('c', '2016-02-01', NULL)
;
All 'a', 'b' and 'c' have points in common, with count a=3D3, b=3D1, c= =3D3.

Note that the 'name'-column here is just to explain what I'm after and= that I have no such column.
