The 2019b DST update [1]disables DST for Brazil. This would take effect starting November 2019. The last DST update in Postgres was 2019a in v11.3 (since this update came in after the recent-most Postgres release).
Since a ~3 month release cycle may be too close for some users, are there any plans for an early 11.5 (or are such occurrences not a candidate for an early release)?
