Okay, I'm pretty sure that's false. Can you back it up at all? So far you provided one example which Bob knocked down trivially. Is there more?

The thing is, I think you're not clear on the difference between operations on sets and operations on used-defined types. Clearly, set theory doesn't include all possible functions over user-defined types. Nor is it supposed to. So, for example, when you mention multimedia, it just looks to me like you're pointing out a lack of, say, digital sound resampling functions, which are properly part of the used-defined type for digital sound, not part of the relational algebra.

I am eagerly awaiting to see what Codd will do in the next decade.
