Description
There doesn't seem to be a good way to upgrade between major versions of postgres. When sharing the volume with a new container with a newer version of postgres it won't run as the data directory hasn't been upgraded. pg_upgrade on the other hand requires (?) old installation binary files, so upgrading the data files from new server container is also difficult.
It would be nice if there was some suggested way of doing this in the readme. Maybe even some meta container which does the upgrading from version to version?

Research direction
Start by reading the repository README and the existing guidance around changing Postgres versions. Investigate how pg_upgrade depends on the old installation binaries and compare that with the old and new server containers. Done means documenting a supported upgrade path, or clearly defining the requirements for a separate upgrade container.
