Here's an example I just thought of that would be great to document:

I have an array of integers. I'd like to also associate some names with
them. I can't do this in the same array, but I can do it in a different
array. But how do I ensure that when I build that array using
name=ARRAY(SELECT name FROM table WHERE id = ANY(id_array) ) that name[1]
actually corresponds to id_array[1]?
