PostgreSQL is a powerful, open-source relational database system that supports a wide variety of applications, from simple web apps to complex analytics platforms. Alongside it, pgAdmin 4 is a comprehensive management tool that provides a graphical interface for managing PostgreSQL databases, making it easier for developers and administrators to interact with their databases.
