This file should consist of one or more sections, each containing a key = value pair. You can also use your Connection Service File.
 
 The title of each section represents a database cluster name (this name is for display purposes only). The dbname parameter is `postgres` by default, and specifies the actual name of the database to connect to. The key-value pairs should contain connection parameters.
