Rudder

I was trying to migrate from rudder 6.2.17 to 7.2.0 (nightly from 5 september).
The migration process displayed some warning about non existing files, but /var/log/rudder/install/rudder-server- contains an error about postgres:

Postgres service is up and running, and I can connect to rudder database.

If I try to play again the rudder migration script, I get other pg-related errors:

The result is that no migration scrpit for database schema is played, and thus the DB is incorrect.

The most apparent symptom is that all nodes are missing reports, and you get errors in relayd (via journald) and webapp (via log files) about mising column reportid:

Sep 05 14:13:28 server rudder-relayd[1809]: ERROR report{queue_id=2DD0A3D062A60B2595DA5FA8ECBA65F2}: rudder_relayd::processing::reporting: output error: column ruddersysevents.reportid does not exist
