Fwiw, what we are doing for apt.postgresql.org and Debian is to support LTS which extends Debian (old)stable to 5 years: https://wiki.debian.org/LTS/ That loosely matches the 5 year support window for Ubuntu's LTS releases, so the oldest Debian and Ubuntu releases often get removed from apt.pg.o around the same time. (It also matches PG's own 5 years of support, so there's rarely any extra backpatching to do.) We are not supporting ELTS for either distro. After around 5 years, supporting all the various extensions starts getting painful because compatibility issues with new upstream versions accumulate. Current top issues are "cmake too old" and "pybuild-plugin-pyproject missing", but it has been worse in the past. There are people keeping the server packages patched for Debian ((old)old)oldoldstable, though: https://wiki.debian.org/LTS/Extended Christoph
