This bit strikes me as dangerous and not related to the original
proposal. I don't care for the load-already-frozen-data part at all,
either. That's not just giving up WAL protection, that's an outright
MVCC semantics violation, in return for which we get ... not much.
Certainly not any speedup in the LOAD itself.
