Hello!

Im working with the ltree [1] datatype and have labels that can not used
directly in ltree and a want to get a tree like strukture ordered by the 
labels.

IE, I've got a table

CREATE TABLE t
(
        tree    LTREE,
        label   TEXT
);

and data like

tree            label
--------------------------
root.1          z
root.2          c
root.2.1        a
root.2.2        b
root.3          i
root.4          f
root.4.1        k
root.4.2        c

I need a VIEW that ordery by "by tree but by label in the same hirachie", 
so the output should be

root.2          c
root.2.1         a
root.2.2         b
root.4          f
root.4.2         c
root.4.1         k
root.3          i
root.1          z

Any idea?

Thanks, 
AXEL.
