This does not look particularly idiomatic, or even type-safe. What you
should have done was use deconstruct_array to get an array of Datums and

(Or, perhaps, use construct_md_array to replicate the input's
precise dimensionality. Not sure if anyone would care.)
regards, tom lane
deconstruct_array() would destroy the arrays dimensions. I would expect
that shuffle() only shuffles the first dimension and keeps the inner
arrays intact.
