The worst I can think of is a large database with a 90/10 mix of
reads to writes -- all short transactions. Maybe someone else can
do better. In particular, I'm not sure how savepoints might play
into a degenerate case.
Since we're always talking about how to do better with hint bits
during an unlogged bulk load, it would be interesting to benchmark
one of those followed by a `select count(*) from newtable;` with and
without the patch, on a data set too big to fit in RAM.

I'm certainly curious to see real numbers.
