Extensions

To keep a standard Cloud installation for all customers and improve our ability to troubleshoot and provide support, we do not provide superuser access to Cloud clusters. Thus customers are not able to install PostgreSQL extensions themselves.

Generally there is no need to install extensions, however, because every Cloud cluster comes pre-loaded with many useful ones:
