Why Is n8n Still Using SQLite Instead of PostgreSQL with My .env Settings?

Hello,
I’m attempting to switch the default database from SQLite to PostgreSQL for my n8n setup, but it continues to use SQLite. I created a new .env file in the root of the n8n folder with my configuration, and while the webhook URL is updating as expected, all database-related settings seem to be ignored.
Here is my .env configuration:
DOTENVN8N_HOST=xxxx VUE_APP_URL_BASE_API=xxxx N8N_EDITOR_BASE_URL=xxxx WEBHOOK_URL=xxxx DB_TYPE=postgresdb DB_POSTGRESDB_DATABASE=n8n-db DB_POSTGRESDB_HOST=xxxx.us-east-1.rds.amazonaws.com DB_POSTGRESDB_PORT=5432 DB_POSTGRESDB_USER=postgres DB_POSTGRESDB_PASSWORD=xxxx
I’m running the latest version of n8n locally using npm run dev. What could be causing the database configuration settings to be ignored?

Below is a list of a few common causes and things you can check:
-
Development Mode Behavior:
When running n8n with "npm run dev" (the development mode), some configuration settings may be hardcoded for local development. Even though your webhook URL is updating, the database settings might not be picked up because the development startup process can bypass or override your .env file for things like the database connection. In production or when running “n8n start,” the .env file is applied as intended. -
Ensure the .env File Is Loaded:
Confirm that the .env file is placed in the working directory from which you’re launching n8n. If you’re starting the process from a different directory or if another environment configuration (such as a docker-compose file or another config file) is present, it may override what’s in your .env file. -
Restart the Process:
After making changes to your .env file, make sure the process is fully stopped and restarted. If the process isn’t restarted, then previously loaded defaults (like SQLite) may persist. -
Consider Using the Production Start Command:
For tests of your database configuration changes, try running “n8n start” rather than “npm run dev” so that the environment is entirely controlled by your .env configuration.
Your current .env configuration is correctly setting DB_TYPE to “postgresdb” along with the other Postgres settings, so the issue is not with the values themselves but with the way the environment file is being loaded in development mode.
By switching to a production start command or ensuring that your development mode process loads the .env file correctly, your PostgreSQL configuration should be recognized.
