Check the man page for lsb_release.

https://manpages.debian.org/buster/lsb-release/lsb_release.1.en.html

You will see that `lsb_release -cs` as used in the postgresql wiki page snippet just prints the running system distribution codename. In Debian, Ubuntu, and others directly supported by pgdg that will “autofill” in the codename into the shell script. As “beowulf” is not supported directly by pgdg, we just have to substitute in the equivalent Debian release codename instead of using the output of `lsb_release -cs`.
