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!

PostgreSQL ships with an interactive console with the command line tool named psql. It can be used both for scripting and interactive usage and is moreover quite a powerful tool. Interactive features includes autocompletion, readline support (history searches, modern keyboard movements, etc), input and output redirection, formatted output, and more.
