I guess DNF reported "disabling postgresql:9.6 stream" among all packages to upgrade and you had to approve the DNF transaction explicitly. If it is not that case, then report a bug against DNF. I think DNF shuld not silently uninstall a module stream. However, if PostgreSQL maintainers did not provide postgresql:9.6 stream for Fedora 35, then DNF has no much options except of aborting the upgrade. Modules are always built for a specific Fedora release and are not portable to another release. > Given the data incompatibility, this is a very unattractive practice.

In Fedora, there is currently no mechanism for transitioning between module streams. E.g. from postgresql:9.6 to postgresql:13. The mechanism <https://fedoraproject.org/wiki/Changes/Module_Obsoletes_and_EOL> was planned for Fedora 35, but it was postponed to Fedora 36. When the machanism is implemented, then DNF will advertise that postgresql:9.6 ends its life on 2021-12-01 and the users are advised to migrate to postgresql:10. Maybe DNF will offer switching from the old stream to the new stream during an upgrade transaction. However, the mechanism won't provide any software-specific migration tools, like convertingdatabase files from one format to another one. Nowdays the end-of-life date can be obtained at <https://pdc.fedoraproject.org/rest_api/v1/component-branch-slas/?branch_type=module&global_component=postgresql&branch=9.6> web page. > Fedora 35 comes obviously without Postgres module 9.6.

I cannot see any change like that on Fedora 35's list of changes <https://fedoraproject.org/wiki/Releases/35/ChangeSet>. Also the maintainers could build postgresql:9.6 for F35 and support it there until 2021-12-01. Maybe they only forgot to build it there. -- Petr
