One other thing I'm wondering about is back-patching. I was originally
thinking of these as back-patchable bug fixes, but changing the binary
format of the aggregate serialization states feels dodgy for a
back-patch.

But then, these functions are only callable in an aggregate context,
and work in pairs. It could be a problem if someone were using them to
pass state between different servers, but I see no evidence of them
being used in that way.

For reference, this will affect the following:
 - int8_avg_serialize()
 - numeric_avg_serialize()
 - numeric_poly_serialize()
 - numeric_serialize()

and the corresponding *_deserialize functions.
