Thanks to all.
The problem is the query.despite don't give me any error returns 0 
features...
This happens because the 'where with the polygon'  [1]...
Anybody knows the origin of that polygon?


select encode(ST_AsBinary(ST_Force_2D("the_geom"),'NDR'),'hex') as 
geom,"n_rua"
     from ruas
         where the_geom && GeomFromText('POLYGON((88071.2044330519 
122184.53,88071.2044330519 124022.08,91531.2955669481          
124022.08,91531.2955669481 122184.53,88071.2044330519 122184.53))',27492)
