I don't much like either of those, because they seem misleading:
what I'd expect from a function named that way is that it returns
the *elements* of the array, not their subscripts.

Come to think of it, do we have a way of doing that directly?  If you
only care about accessing the array elements, it seems like dealing in
the subscripts is just notational tedium.  Perhaps there should be
array_expand(anyarray) returns setof anyelement, in addition to the
subscript generation function.

On the question of being too long, I could live with
generate_subscripts().
