I don't think array_in() should need to care now whether the array elements are domains, whereas in the original design there would have had to be explicit support for domains added to the array code. There might be some performance issues, ie, making sure the stack of array_in and domain_in can cache data at both levels, but that seems eminently solvable. regards, tom lane
