That's a *lot* of extra columns for such a
marginal feature. More
likely we'd do something like log a blob that has a serialized list of
everything changed. (This would require actually figuring out
everything that was changed, of course, which already complicates
things and probably slows them down.) If we want to revert, we'd load
up the blob and build the queries from it.
That sounds feasible, and allow blobs to expire after a certain length
of time unreverted if the space gets onerous.
What, a few kilobytes per rename? At a handful of renames per day?
Not likely to be a problem.
