What potential pitfalls should be considered when setting up cronjobs for PHP scripts to interact with a database?

When setting up cronjobs for PHP scripts to interact with a database, potential pitfalls to consider include ensuring proper error handling to catch any issues that may arise during script execution, setting up appropriate permissions and security measures to protect sensitive data, and scheduling the cronjobs at appropriate intervals to avoid overwhelming the database server. 

// Example of setting up proper error handling in a PHP script interacting with a database
try {
    // Database connection code
    $conn = new PDO("mysql:host=localhost;dbname=myDB", "username", "password");
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    // Database interaction code
    // ...

} catch(PDOException $e) {
    // Handle any database connection or query errors
    echo "Error: " . $e->getMessage();
}
