[postgis-users] select the interior parcels smaller than 25 hectares

[fsalas]

Hi,
I  used this SQL for select the interior parcels and obtained all interior 
parcels on the map..

SELECT ST_InteriorRingN((the_geom),s)
FROM datnivel3, generate_series(1,(SELECT max(ST_NumInteriorRing(the_geom))
FROM datnivel3)) s
 WHERE ST_NumInteriorRing(the_geom) > 0
AND ST_InteriorRingN(the_geom,s) IS NOT NULL

.However, I need select from "datnivel3" table, only the parcels  smaller 
than 25 hectares,
How can I implement this?

Thank you,

 Salas
