pgAdmin
pgAdmin is an open-source administration and management tool for PostgreSQL and its related database systems. It provides a graphical user interface (GUI) for performing database tasks such as querying, server management, and schema design, making it easier to work with PostgreSQL without relying solely on command-line interfaces. The tool supports multiple PostgreSQL versions and includes features like data import/export, backup/restore, and real-time monitoring.
Developers should learn pgAdmin when working with PostgreSQL databases to streamline administration, debugging, and development workflows, especially in environments where visual tools improve productivity over command-line operations. It is particularly useful for database administrators, backend developers, and data analysts who need to manage schemas, run complex queries, or monitor database performance without deep command-line expertise. Use cases include setting up new databases, optimizing queries with visual explain plans, and managing user permissions in team-based projects.
