Anyway, yes, you could get the newer zoneinfo source files and run them
through zic, but it's hard to see why that would be a smarter thing to
do than a database update. There are known data-loss bugs in the minor
version you're running, and you ought to be a lot more worried about
those than about whether Postgres is a week off about the next DST
transition.
