Hello,
is it possible to obtain the minimum and the maximum single element of
an array column?
Example:
[1, 2 ,5]
[3, -1, 6]
[9, 18,-4 ]
I'd just like to make a query that gives me the min (-4) and the max(18)
of the column. Is that possible without a function? Thanks

If you do not mind non standard, how about:
SELECT DISTINCT ON(id_father) * FROM children ORDER BY id_father,
child_age;

Hello, everybody!
I've trouble to make a "simple"(?) query...
The following table is an example:
table: children
id_father | child_name | child_age
--++
1 | John | 2
1 | Joe| 3
1 | Mary | 4
1 | Cristine | 4
