https://www.postgresql.org/about/news/1960/
PostgreSQL 11.5, 10.10, 9.6.15, 9.5.19, 9.4.24, and 12 Beta 3 Released!

"This update also contains tzdata release 2019b for DST law changes in 
Brazil, plus historical corrections for Hong Kong, Italy, and Palestine. 
This update also adds support for zic's new -b slim option to reduce the 
size of the installed zone files, though it is not currently being used 
by PostgreSQL."
