What are the advantages of using PDO (PHP Data Objects) over specific database functions like PostgreSQL Functions in PHP development?

Using PDO (PHP Data Objects) over specific database functions like PostgreSQL Functions in PHP development offers several advantages. PDO provides a consistent interface for accessing different types of databases, allowing developers to write code that is more portable and easier to maintain. Additionally, PDO supports prepared statements, which help prevent SQL injection attacks by automatically escaping input parameters. Finally, PDO simplifies error handling by throwing exceptions that can be caught and handled in a consistent manner. 

// Using PDO to connect to a PostgreSQL database
try {
    $pdo = new PDO('pgsql:host=localhost;dbname=mydatabase', 'username', 'password');
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch (PDOException $e) {
    echo 'Connection failed: ' . $e->getMessage();
}
