Hi all.
=C2=A0
I'm trying to count() overlapping entries (timestamp-ranges, tsrange) = and have the following test-data:
=C2=A0
create table event(
    id SERIAL PRI=
MARY KEY,
    start_time ti=
mestamp NOT NULL,
    end_time TIME=
STAMP,
    tsrange TSRAN=
GE NOT NULL
);

CREATE INDEX event_range_idx tsrange);

-- Populate tsrange in this trigger
CREATE OR REPLACE=
 FUNCTION event_update_tf() returns TRIGGER AS $$
BEGIN
    if NEW=
.end_time IS NOT NULL then
        NE=
W.tsrange =3D tsrange(NEW.start_time, NEW.end_time, '[]');
    else
        NE=
W.tsrange =3D tsrange(NEW.start_time, null, '[)');
    end if=
;
    RETURN=
 NEW;
END;
$$ =
LANGUAGE p=
lpgsql;

CREATE TRIGGER event_update_t BEFORE INSERT OR UPDATE ON event
FOR EACH R=
OW EXECUTE PROCEDURE event_update_tf();

insert into event=
(start_time, end_time)
    values=
('2015-12-20', NULL)
    , ('2015-12-2=
0', '2015-=
12-31')
    , ('2015-12-2=
5', '2016-=
01-01')
    , ('2015-11-2=
0', '2015-=
11-24')
    , ('2016-02-0=
1', '2016-=
02-03')
    , ('2016-02-0=
1', '2016-=
02-04')
    , ('2016-02-0=
1', NULL)
;
What I'd like is output like this:

=C2=A0count
=E2=94=80=E2=94=80=E2=94=80=E2=94=80=E2=94=80=E2=94=80=E2=94=80
=C2=A0=C2=A0=C2=A0=C2=A0 1
=C2=A0=C2=A0=C2=A0=C2=A0 3
=C2=A0=C2=A0=C2=A0=C2=A0 3
(3 rows)
=C2=A0
Something like:
SELECT count(*) FROM event group by (tsrange with &&);
=C2=A0
PS: In my real query the tsrange and other data is the result of a que= ry involving multile tables, this is just a simplified example to deal with= the "group by tsquery"
=C2=A0
Thanks.
