Selectivity misestimations can have a huge impact on query
performance, and that could be a big deal if there's a big regression
on some queries.

But, the beta period could be enough to detect any issues there. I'll
leave that decision to committers or commitfest managers I guess.

But Tom hasn't yet, and even if he does, we'd have to be done with the
review within this week.

In any case, I intend to go on with the review later today, and at
first look the patch seems in good shape (though it'll take a deeper
look before I make that my official review). Most other patches in
need of review are a bit complex for my knowledge of the code base,
and I already started reviewing this one. We could perhaps be done by
the end of the week.

We could defer that decision to within 4 days. If we're done, we're
done. If we're not, move to next CF.
