What are the variants of PostgreSQL?
PostgreSQL has several variants, including EDB Postgres, which is a commercially supported version of PostgreSQL with additional features and support services. Another variant is Citus, which is an extension that enables distributed database functionality for PostgreSQL, allowing it to scale out across multiple servers. Additionally, there are community-driven forks of PostgreSQL, such as Greenplum and TimescaleDB, which are tailored for specific use cases like analytics and time-series data management. **
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. This connection is typically made using a programming language-specific library or driver like psycopg2 for Python or pg for Node.js. 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. **
