Setting up PostgreSQL in Linux

PostgreSQL, often referred to as "Postgres," is a powerful, open-source object-relational database management system (RDBMS). It is widely used for handling large-scale data, supporting advanced data types, and ensuring data integrity. Postgres is a popular choice in industries like finance, web development, and data analysis due to its reliability, robust feature set, and active community. With features like transactional integrity, concurrency, and support for modern applications, PostgreSQL is highly regarded for building scalable, secure, and high-performance database systems.
