N8n won't restart after PostgreSQL database update, error is migration failed

Describe the issue/error/question

I’m running n8n on:

  • self-hosted mode on aws with Fargate (docker)
  • using RDS Postgres and EFS for storing n8n data.
  • version is latest.

The rds instance got restarted after an update while the n8n app was running, since then the n8n app keeps crashing at application start-up.

What is the error message (if any)?

Migration "DeleteExecutionsWithWorkflows1673268682475" failed, error: relation "execution_entity" does not exist.

Running a docker container on my laptop while using the same database gives me the same error message.

I’ve looked into the database and the relation still exists, I’ve also looked in the migrations table but I won’t find the DeleteExecutionsWithWorkflows1673268682475 line in it.

Would someone have a clue on how to resolve this without losing any data ?
Many thanks

Hey @Jon

Worked like a charm, many thanks !


hey @Jon running into the similar problem using the latest 0.213.0 (2023-01-27) on a postgres DB. We already have

  74         - name: EXECUTIONS_DATA_PRUNE
  75           value: "true"
  76         - name: EXECUTIONS_DATA_MAX_AGE
  77           value: "186"

Any ideas how to recover from this?

Quick update on the above, we had a massive 300Gb execution_entity table with workflows that never terminated. the migration was stuck trying to apply schema changes. We’re investigating whether the non terminating nodes are issues on our end (ie node setup) or something deeper. If you’re facing similar problems, trying truncating your execution_entity (you will loose execution history) and continue with the migration

I’m having the same problem, can’t upgrade to latest version because the migration never finish and leaves the app in a “non-responding” state.

using Docker and Postgres as database

How do I do this ?


you’ll need to connect to your n8n database (whatever database you’re using) and delete data in the execution_entity table.

  • If sqlite, you probably need to ssh into where you’re running n8n and find it (default location: The database file is located at: ~/.n8n/database.sqlite).

  • We were using postgres, so connect with the right permissions to delete. You then could delete data in execution_entity using sql.

There’s two dates you can filter on (startedAt and stoppedAt) or just go yolo and delete everything. We left last 3 days which is never looked at in case of successful workflows but your requirements might be different. I recommend viewing the data you want to delete before deleting. good luck

Just in case anyone comes after me using the same context :

Cloudron managed N8N (docker, postgres)

push the Postgres button on the terminal web view :


on the sql cli that opens use :

DELETE FROM execution_entity;

or even this to wipe it (my use case)

TRUNCATE execution_entity;
