The biggest change in v3 is the no change at all to the code, but a

offloading undocumented (or if I documented it, it would only be for
this one edge-case) magic on the oid_array API. Instead I'm just
making this patch a bit more complex.

I think that's fair. Thanks for going along with me on the thought
