I’m encountering difficulties in establishing a connection between my PostgreSQL database and a basic Node.js server. I’ve successfully set up the database and Node.js environment, but when I attempt to query the database using my Node.js application, it fails to retrieve or send data. I’ve configured my connection string correctly, and the PostgreSQL server is running without errors. What could be missing or misconfigured in my setup to cause this issue? Any advice would be appreciated. Check out the Wikipedia page on PostgreSQL for more context.
