// PostgreSQL Installer Test (Simplified)
//
// This test script demonstrates how to use the PostgreSQL installer module to:
// - Install PostgreSQL using nerdctl
// - Create a database
// - Execute SQL scripts
// - Check if PostgreSQL is running

// Define test variables

let postgres_port = 5433;  // Use a non-default port to avoid conflicts
let postgres_user = "testuser";
let postgres_password = "testpassword";
