Well, the perfect is the enemy of the good as they say. By all means,
let's get rid of the O(n^2) behaviour in 9.5, but let's get a basic
version into 9.4.

I'm not aware of any open issues in the basic patch, other then
scaling the reported calling statistics by nloops, which should be
trivial. I'll post an updated patch later today.
I don't really expect all the add-on patches to make it into 9.4 -
they don't seem to have gotten much attention yet - but at least
the inverse transition functions for the basic arithmetic aggregates
should be doable I hope.
