Hello, Thanks everyone for your input. Then, it sounds like I won't use an array of foreign keys. I was just curious about the array functionality. However, I didn't think about setting up a view above the intermediary table with an array_accum, now I have never heard of array_accum. I did some research in the online doc. It's a cool functionality, but what's the performance of it? Would using an array_accum slow down a view?
