hi

I have menu table: id          | integer | not null default 
nextval('public.menu_id_seq'::text) parent_id   | integer | description | text    |

I do select:
test=> SELECT * FROM connectby('menu','id','parent_id','2',0,'~') t(id 
integer, parent_id integer, level int, branch text); id | parent_id | level |   branch
----+-----------+-------+-------------  2 |           |     0 | 2  4 |         2 |     1 | 2~4  7 |         4 |     2 | 2~4~7 10 |         7 |     3 | 2~4~7~10 16 |        10 |     4 | 2~4~7~10~16  9 |         4 |     2 | 2~4~9

How am I able to select description file from menu table, not only id, 
parent_id, level, branch fields?

Try a join with the original table:

SELECT t.*, description FROM connectby('menu','id','parent_id','2',0,'~') 
AS t(id integer, parent_id integer, level int, branch text), menu 
WHERE t.id = menu.id
