Say I have a field of ints, as for example created by with ordinality or generate_series, is it possible to group by a range? eq

1,2,3,4,5,6,7,8,9,10

1 1

2 1

3 1

4 2

5 2

6 2

7 3

8 3

9 3

10 4

select num, ceiling(CAST (num as float)/3) as grp from Agg
    ("num" int);
   
INSERT INTO Agg
    ("num")
VALUES
    (1),
    (2),
    (3),
    (4),
    (5),
    (6),
    (7),
    (8),
