Frequently Asked Questions

What is a PostgreSQL connection string?

A PostgreSQL connection string (also called a database URL or DSN) is a single URI that contains all the information needed to connect to a PostgreSQL database — the username, password, host, port, and database name.

Most database platforms like Supabase, Neon, AWS RDS, and Railway provide this string in their dashboard. It's the standard way to configure database connections in web applications, ORMs, and tools.

PostgreSQL connection string format

The standard format is:

postgresql://user:password@host:port/database?sslmode=require

user — database username

password — database password

host — server address

port — default 5432

database — database name

sslmode — SSL connection mode

Both postgresql:// and postgres:// prefixes are accepted.

Where to find your connection string

Go to your database provider's dashboard
Navigate to the connection settings or database configuration section
Look for "Connection string", "Database URL", or "Connection pooling URL"
Copy the full connection string (starts with postgresql:// or postgres://)
Make sure the string includes your password (may need to reveal or replace placeholder)
