Sorry, I was being imprecise there. What I meant was that an opclass
that abused the reconstructed-value storage for something else might
have problems supporting index-only scans.
If we think opclasses might need private storage for index searches, we
should add that as a new part of the API, not tell them to misuse this
part.
