[postgis-users] creating view as simplified geometry fails

[G. Allegri]

Hi list.
I'm trying to create a view for a simplified polygon features table.

create view prova as select simplify(wkb_geometry,20) as simpgeom from
sections01

I receive (translated from italian): the query was succesfull, but
without results,

The view has been created, but is empty.
The select simplify(... alone works fine.

What am I doing wrong?
