How to loop through multi-dimentional array in PL/PGSQL

[VENKTESH GUTTEDAR <venkteshguttedar@xxxxxxxxx>]

Hello,

    Please help me in accessing multi-dimentional array in postgresql PL/PGSQL.

    for i in array_lower(product_list, 1) .. array_upper(product_list, 1)

    LOOP
        product_list[i][0];

    END LOOP;

    Is the above code right?

    Or is there any other way to access, i am getting null for product_list[i][0];

    Any help would be appreciated.
