I am using the PostgreSQL binary downloads for Debian from your apt repositories. I am about to upgrade from Debian 9 to Debian 10 and would like comments for my plan: 1. I will follow Debian's instructions for upgrading from 9 to 10. 2. Before I start the actual upgrade, I will: + ensure all is up-to-date for my PostgreSQL as well as the rest of my system + temporarily comment out the PostgreSQL links in /etc/apt. + stop the pgsql server and prevent auto-restart upon reboot 3. After the successful upgrade I assume I will: + update the apt sources for PostgreSQL with the new name (buster) + update as usual + restart the pgsql server and resume auto-start upon reboot Thanks for your help. Blessings, -Tom
