Rezgui,
This is a postgis question, I would suggest the postgis forums.
Right off the bat the the sql does not seem to be problematic, as it is an example from the postgis help.
I would venture a guess that you have not granted privs on the public.geometry_columns table...
Good luck,
Kasia

May be not related, but try to never insert a primary key: as you insert
1 for road_id, the PK sequence is NOT incremented; use default instead.
