Seems dangerous as heck; certainly it would have side-effects far more
wide-ranging than just making this particular function work.
A safer answer is to split array_agg into two functions,
array_agg(anynonarray) -> anyarray
array_agg(anyarray) -> anyarray
I rather imagine you should do that anyway, because I really doubt
that this hack is operating quite as intended. I suspect you are
producing arrays containing arrays as elements, not true 2-D arrays.
That's not a direction we want to go in I think; certainly there are
no other operations that produce such things.
