I have several machines that have version 11 instances on them. These are all Debian or Ubuntu machines. All of them are pointed to the Postgres repositories fro the Postgres binaries
deb http://apt.postgresql.org/pub/repos/apt/ buster-pgdg main dpkg -l shows: ii postgresql-11 11.6-1.pgdg100+1 ii postgresql-12 12.1-1.pgdg100+1 ii postgresql-client-11 11.6-1.pgdg100+1 ii postgresql-client-12 12.1-1.pgdg100+1 ii postgresql-client-common 210.pgdg100+1 ii postgresql-common 210.pgdg100+1 ii postgresql-contrib 12+210.pgdg100+1 ii postgresql-server-dev-11 11.6-1.pgdg100+1 Googling around, I found this link: https://scottlinux.com/2015/11/14/upgrade-postgresql-on-debian-jessie-with-pg_upgradecluster/ I plan on upgrading one of the test instances right away. Is the information in this link the best way to do this in a Debian environment? I did look at the pg_upgrade documentation, and it looks like I could really make a mess if I misunderstand even one step.
