Added that now.

Thanks! Can you amend your commit to link the upgrade docs so it shows up in the changelog? Eg:

This update requires manual migration of databases. Instructions can be found in the [Solus Help Center](https://help.getsol.us/docs/user/software/development/postgresql#updating-to-17).

Additionally, be aware that this is not something that can be landed during the ISO release freeze as 1) it's very much not a leaf package, and 2) included in the actual ISO (the CI missed that, apparently :disappointed:)

No problems, updated commit message and Github message.
