Postgres volume 100% full - can't access n8n to export workflows

Hi team,

My n8n Postgres volume is at 100% capacity and I can't access n8n to export or delete my workflows.

Could you please temporarily increase the volume size to 2-3GB so I can:

  1. Access n8n

  2. Export my workflows

  3. Clean up execution data

I'll reduce usage immediately after and won't need the extra space long-term.

I'm on the Hobby plan and can't upgrade right now.

Thank you!

You will need to temp upgrade your plan. Set the volume size to 3G, clean the db and downgrade.

check https://docs.railway.com/reference/volumes

I am not sure the staff can assist with a temporary increase in volume.

otherwise, you can connect directly to the Postgres DB instance. check the space the logs (execution tables) are using.

SELECT schemaname, tablename, pg_size_pretty(pg_total_relation_size(schemaname||'.'||tablename)) AS size FROM pg_tables WHERE tablename LIKE '%execution%' ORDER BY pg_total_relation_size(schemaname||'.'||tablename) DESC;

Then do some clean up
