For what he was doing, it seemed perfectly acceptable.
This comes back to the point I've been making during the pghackers
discussion: start-of-transaction time has clear uses, and
exact-current-time has clear uses, but it's not nearly as obvious
why you'd need start-of-statement time in preference to either of
the others.
