Do you really need to use intarray, rather than the built-in gin array indexing features? Yeah, the intarray implementation is probably a shade faster, but it's faster precisely because it doesn't handle cases like null entries. If you're in need of that, my suggestion is to ditch intarray. regards, tom lane
