PostgreSQL horizontal scalability

I couldn’t find any resource that says PostgreSQL has native horizontal scalability. Please provide a reference to this stated capability.

Let me google that for you.

It is stated on the main Azure page for the product:

Here are the docs for this feature:—hyperscale-citus



The lesson was going through history of PostgreSQL, its open source root, why developers love and then this was mentioned. It seemed that horizontal scalability is a native feature of Postres, it is not. Citus is a Postgres extension.


The official site doesn’t even mention this, I agree that Azure offers this option.
