Right. It doesn't _look_ that way from the graph, but that's because I only
graph total DB size. I expect if I graphed data and index size separately,
it would be evident.
At this point, I'm going to assume that my question of, "Is this 4x bloat
strange enough to warrant further investigation" is "no". It seems like
this amount of bloat isn't terribly unusual, and that the people working on
improving this sort of thing already have enough examples of it.
Thanks to everyone for the replies.
