Unknown primary key for table settings in model Setting. After PostgreSQL database migration

**Problem: We are currently trying to upgrade our Foreman instance. To test this upgrade, I made a clone of the current machine and dumped the foreman and candlepin db from our external PostgreSQL 9.6 server. After dumping I installed PostgreSQL 9.6 locally on the clone and imported the Foreman and Candlepin db’s to the local PostgreSQL instance (MongoDB is already running locally btw). Then I changed the database host to localhost in the files /etc/foreman/database.yml and /etc/candlepin/candlepin.conf.

As soon as I start the Foreman I get the following error:

Unknown primary key for table settings in model Setting.
Can not validate uniqueness for persisted record without primary key. (ActiveRecord::UnknownPrimaryKey)

Expected outcome:

**Foreman and Proxy versions: 1.21.4

**Foreman and Proxy plugin versions: 1.21.4

**Distribution and version: Centos 7

**Other relevant data: Log Snippet

Web application could not be started

Hey.

Check if you migrated also indices. Paste the pgdump/pgrestore commands please.

Hi,

Thanks for your reply

The commands that I used to create the PostgreSQL backups are:

foreman-maintain advanced procedure run backup-offline-candlepin-db --backup-dir /tmp/candlepin/
foreman-maintain advanced procedure run backup-offline-foreman-db --backup-dir /tmp/foreman

Ans the restore commands that I used are

pg_restore -d foreman foreman.dump
pg_restore -d candlepin candlepin.dump

I see you marked the thread as resolved, I suppose you haven’t solved it tho.

Can you dump database schemas on both servers and compare it? There must be a PK missing on the new one.

I didnt stop the foreman instance while backupping the postgresql database.

I just stopped the foreman instance and backupped the data from the postgresql server.
