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.
