There is something wrong here. On Debian Buster/unstable, using
system tzdata (2019a-1), if /etc/timezone is "Etc/UTC":

11.3's initdb adds timezone = 'UCT' to postgresql.conf
12beta1's initdb add timezone = 'Etc/UCT' to postgresql.conf

Is that expected behavior? Docker users are complaining that "UCT"
messes up their testsuites. https://github.com/docker-library/postgres/issues/577
