 By following this guide, you can seamlessly integrate the `nanoid_optimized()` function into your projects and enjoy the
 benefits of its optimized performance.
 
+### LEAKPROOF Setting
+
+#### Default Configuration
+The `nanoid()` function is configured without the `LEAKPROOF` attribute by default to ensure compatibility across diverse 
+environments, including cloud platforms and managed services, without the need for superuser privileges.
+
+#### When to Enable LEAKPROOF
+Enabling `LEAKPROOF` is optional and beneficial in environments that require enhanced security measures, such as those 
+utilizing row-level security (RLS). This setting should be considered if you have superuser access and seek to further 
+restrict information leakage.
+
+**Note:** To apply the LEAKPROOF attribute, uncomment the LEAKPROOF line in the function definition. This setting 
+is permissible only for superusers due to its implications for database security and operation.
