You could try select spaces(pointer::int4) || Number; Where spaces() is a
function that inserts "pointer" number of spaces (or dashes if you want to
create your own function). Not sure if spaces() exists in Postgres or not,
but it seems I read about it or a similar function somewhere.

Subject: [GENERAL] Tree structure
I can't figure this one out. I need a tree structure like this
Number Pointer
1 0
2 1
3 1
4 2
5 0
6 1
7 5
This should somehow show up like this
Number
1
2
4
3
6
5
7
The whole excercise is because I'd like to show a tree structure:
1
- 2
- - 4
- 3
- 6
5
- 7
Is this possible with PostgreSQL?
