Looping through Arrays

Hi

I want to be able to loop through an array. The code I have used in the past is:

FOR i IN array_lower(arrayvar,1) .. array_upper(arrayvar,1) LOOP
currentvalue:=arrayvar[1][i];
RAISE NOTICE '%', currentvalue;
END LOOP;

But now I need to loop through the whole array, not just the one element. I want to do something like:

FOR j in ....LOOP
    FOR i IN array_lower(arrayvar,1) .. array_upper(arrayvar,1) LOOP
    currentvalue:=arrayvar[j][i];
    RAISE NOTICE '%', currentvalue;
    END LOOP;
END LOOP;

How to I set the upper and lower bounds for j?

FOR j IN array_lower(arrayvar, 2)..array_upper(arrayvar, 2) LOOP
