Be gentle just learning all this

I have successfully learned how to use ST_Polygonize to convert a 
LINESTRING table to POLYGON
using this syntax, maybe could be neater..

SELECT ST_AsEWKT((ST_Dump(test2.polycoll)).geom) AS geomtextrep
FROM (SELECT ST_Polygonize(the_geom) AS polycoll
FROM (SELECT the_geom FROM maxt) AS test)AS test2;


now how do I identify the value of each Polygon I have??
There is another column that identifies value of the LINESTRING
