Indeed, in https://www.postgresql.org/support/versioning/: Upgrading Major versions make complex changes, so the contents of the data directory cannot be maintained in a backward compatible way. A dump/reload of the database or use of the pg_upgrade application is required for major upgrades. We also recommend reading the upgrading section of the major version you are planning to upgrade to. You can upgrade from one major version to another without upgrading to intervening versions, but we recommend reading the release notes of all intervening major versions prior to doing so. > 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? #f seems a good option since it forces users to update manually when they require it, no magic updates involved. Maybe we should add a comment about why the default is #f, and point to the url of the documentation about upgrades. > - add a news item to be displayed during "guix pull"? I think a news item is necessary. Sorry I should have thought about it with the patch, let me know if you'd wish I write this patch + news item. > Andreas > -- Best regards, Nicolas Graves
