I would expect that shuffle() only shuffles the first dimension and

This argument is based on a false premise, ie that Postgres thinks
multidimensional arrays are arrays-of-arrays. They aren't, and
we're not going to start making them so by defining shuffle()
at variance with every other array-manipulating function. Shuffling
the individual elements regardless of array shape is the definition
that's consistent with our existing functionality.
Hey Tom,
thank you for clarification. I did not know that. I will make a patch
that is using deconstruct_array().
