PostgreSQL connection strings embedded in your application can take two different forms: the key-value notation or the postgresql:// URI scheme. When it comes to using psql though, another form of connection string is introduced, with command line options -h -p -U and environment variable support.

In this short article you will learn that you can use either of the three different forms in psql and thus easily copy & paste you application connection string right at the console to test it!
