Another variant is Citus, which is an extension that enables distributed database functionality for PostgreSQL, allowing it to scale out across multiple servers.

How does a web server access the PostgreSQL database?
A web server can access a PostgreSQL database by establishing a connection to the database using the appropriate credentials such as username and password.

Once the connection is established, the web server can send SQL queries to the database to retrieve or manipulate data as needed. The results of these queries are then processed by the web server and returned to the client. **
