This is covered by bug 2140. I've submitted an initial patch for that bug, but
it's not quite complete yet.
This bug should probably be marked as a duplicate, unless we want 'stat=0' to
also clear stats. That will require more changes to the way types are inferred
- e.g. do we special-case 0, or do we also allow 'stat=1'? And what would that
mean? I think the delete operator makes more sense.

"delete ARRAY" and "delete ARRAY[index]" should clearly work for both plain and
aggregate arrays. I can go along with a "delete SCALAR" too.
Using assignment to reset is less appealing.
