Issue with PostgreSQL 16

[RaimundasZutautas]

Hello,
Today Watchtower automatically updated my PostgreSQL to v16 and my koillectionDB cannot start.
It showing in logs that version is incompatible:
"2023-09-16 19:13:00.619 UTC [1] FATAL: database files are incompatible with server
2023-09-16 19:13:00.619 UTC [1] DETAIL: The data directory was initialized by PostgreSQL version 15, which is not compatible with this version 16.0 (Debian 16.0-1.pgdg120+1)."

Maybe someone knows how to fix it?
My koillection running on Synology NAS Docker.

Hello,

PostgreSQL major versions are not compatible with each other and always require manual upgrade of the database. The doc can be found here: https://www.postgresql.org/docs/current/upgrading.html

If you plan to do this, I strongly suggest making a backup of your database first.

Alternatively, you can update the docker-compose file and specify version 15 for PostgreSQL.
