PostgreSQL version 15 is not compatible with version 16.0 (Debian 16.0-1.pgdg120+1).

[KLISCHE-HW]

I have installed easypanel.io in an Ubuntu 22.04 enviroment and got suddenly this error message:
The data directory was initialized by PostgreSQL version 15, which is not compatible with this version 16.0 (Debian 16.0-1.pgdg120+1).

The PostgreSQL data directory is not compatible between major versions, so the quick fix is to not use postgres:latest but to use the more specific postgres:15 to be compatible with your data directory.

There is more discussion on upgrading between major versions in #37
