Not only are SAAS products just database wrappers, but many other products also enhance the capabilities of Postgres and MySQL through the use of a third-party product, such as leveraging DuckDB's analytical capabilities on PostgreSQL. Whether these two different databases can achieve seamless integration remains to be observed.
You might be right that Postgres isn't for every use, but I think we should enhance its database abilities with extensions. Not everything is set in stone, and every product has its own worth. The world isn't just black or white. Postgres' capabilities in transaction processing (TP) has improved over 30 years, Much of its code logic is designed based on previous data volumes and data models, and it needs to keep pace with the times. So, adding analytical, AI, and distributed computing features through extension is really useful.
