migration to Postgres 14 for bag, kanboard and cloud
Migration to Postgres14 for the 3 services I am using in production (addressing partly #92) I have not migrated the other one as I cannot test them. If you want, I can update this merge request with the migration for the other services, but without any ability to test them.
I tried to be as precise as possible for the instructions on how to migrate. I decided to put a dedicated section in each README. We might centralize this in a single file at the root of the repo if you think it is better, let me know.
