Hello, I have just pushed this commit https://issues.guix.gnu.org/74006 that changes the default postgresql version from 10 (which has a CVE) to just the postgresql variable (now at 15).
Since as I understood changing postgresql versions requires a (manual?) update of the database format, I am wondering whether we should - instead again choose a default value of a specific version? or maybe #f and force the user to choose one themselves? - add a news item to be displayed during "guix pull"?
