Hello Christoph,According to the LTS files, you plan to take care of postgresql-9.6 security updates for stretch.
I reserved postgresql-9.6 for you in https://salsa.debian.org/security-tracker-team/security-tracker/-/blob/master/data/dla-needed.txt AFAICS postgresql-9 is not supported upstream since 2021-11 https://www.postgresql.org/support/versioning/ so if this changes anything in your plans please let me know. Cheers! Sylvain Beucler Debian LTS Team
