> Array indexes currently perform UPSERTs by unconditionally deleting the old array contents
and inserting the new array contents. A "merge-join" inspired approach could be used here
instead, where we iterate through the already sorted old and new arrays, compare the elements
at each step, and selectively perform an insert / delete.
