After upgrading from 9.5 to 10, new db has no tables

[mark-anders]

I ran the upgrade from 9.5 to 10 and it appeared that everything went smoothly. However, when I inspected the database using psql, the databases do not seem to have any tables defined. Any idea what could be wrong?

Here's a transcript:

docker run --rm \
> -v /data:/var/lib/postgresql \

The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.

The database cluster will be initialized with locale "en_US.utf8".
The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "english".

Data page checksums are disabled.

Success. You can now start the database server using:

    pg_ctl -D /var/lib/postgresql/10/data -l logfile start

You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run initdb.

If pg_upgrade fails after this point, you must re-initdb the
new cluster before continuing.

Adding ".old" suffix to old global/pg_control               ok

If you want to start the old cluster, you will need to remove
the ".old" suffix from /var/lib/postgresql/9.5/data/global/pg_control.old.
Because "link" mode was used, the old cluster cannot be safely
started once the new cluster has been started.

Upgrade Complete
----------------
Optimizer statistics are not transferred by pg_upgrade so,
once you start the new server, consider running:
    ./analyze_new_cluster.sh

Running this script will delete the old cluster's data files:
    ./delete_old_cluster.sh
mark@:xxxx/data$ ls

Just a followup. I thought if I removed the ".old" suffix from /var/lib/postgresql/9.5/data/global/pg_control.old, I would be able to restart a 9.5 instance, however, all of the data is gone from that too.
