I am using two polygon tables in postgis (A and B ). I need to make a vector file that incorporates information of the overlapped polygons B intersecting each polygon on (A).

I can make a single shapefile for each polygon of A with the resulting intersections and other info of B.

Is there a way in which I could "merge" all these resulting polygons (each with its own attributes) into a single file ?

I was thinking that maybe using an array column but I also need other info related to the intersection like area and percentage of coverage.

There should be no problem with what you are asking - a shapefile can contain multiple polygons. Can you edit your question to explain the process you are trying to use and the problems you are having with it? – BradHards Feb 16 '13 at 22:03
