Yeah. I intend to install 2019b (or later?) before our next minor releases.

We do not consider tzdb updates to be a release-forcing issue. The fact that we ship tzdb at all is just a courtesy to PG users who are on platforms that lack a more direct way to get tzdb updates. The usual recommendation on well-maintained production systems is to configure PG with --with-system-tzdata, then rely on your platform vendor for timely updates of that data.
It should be noted that this is not true on Windows -- on Windows we cannot use the system timezone functionality, and rely entirely on the files we ship as part of our release.
