Update to Zammad 6.4, and perform major dependency updates including postgres 17.

[mgruner]

This includes a major update for the postgres dependency from 15 to 17, which requires manual action to upgrade the postgresql cluster data to the new version.

i guess link to upgrading docs will be added in the relase notes?

[mgruner]

Yes: https://www.postgresql.org/docs/17/upgrading.html, I will add it to the tag description.

Maybe pointing to https://github.com/tianon/docker-postgres-upgrade for upgrading a persisting docker volume might be useful.

@waja thanks for the tip, added to https://github.com/zammad/zammad-docker-compose/releases/tag/v13.0.0.

@mgruner IMPORTANT: Using the docker method suggested by @waja breaks/prevents the database from starting because it's using the 17:bookworm image to upgrade instead of 17:alpine that is used in zammad-compose!

I got an error: database "zammad_production" has no actual collation version, but a version was recorded that could only be fixed by moving to 17:bookworm image in the zammad compose file. (See this: https://stackoverflow.com/a/78572273)

Just as an idea, maybe this is a way easier solution to do the upgrade. Since I was searching for an easy way.

It means to just change the image for the upgrade and switch it back afterwards. Maybe with the environment PGAUTO_ONESHOT: yes

This is really the easiest solution.
Just stop the stack and enter (change the variables and your path to the db):

docker run --name pgauto -it \ --mount type=bind,source=/var/lib/docker/volumes/zammad_postgresql-data/_data,target=/var/lib/postgresql/data \ -e POSTGRES_DB=zammad_production \ -e POSTGRES_USER=zammad \ -e POSTGRES_PASSWORD=zammad \ -e PGAUTO_ONESHOT=yes \ pgautoupgrade/pgautoupgrade:17-alpine

Start the stack.
Finished.
