Laravel makes connecting with Postgres databases and running queries extremely simple out of the box. The Postgres database configuration for your application is located at Laravel Project Root Folder, config/database.php. In this file you may define Postgres database connection for your Laravel Application.

'pgsql' => [
    'driver'   => 'pgsql',
    'host'     => env('DB_HOST', 'localhost'),
    'database' => env('DB_DATABASE', 'forge'),
    'username' => env('DB_USERNAME', 'forge'),
    'password' => env('DB_PASSWORD', ''),
    'charset'  => 'utf8',
    'prefix'   => '',
    'schema'   => 'public',
],
