pgAdmin is the leading open-source graphical management tool for PostgreSQL. Designed as a comprehensive administration and development platform, pgAdmin provides a rich web-based interface for managing PostgreSQL databases, writing queries, monitoring performance, and administering server resources. It is the official PostgreSQL management tool and is maintained by the PostgreSQL community.

pgAdmin 4, the latest generation (version 9.0, released March 2026), is built as a modern web application with Python (Flask) on the server side and ReactJS on the client side. It supports PostgreSQL 10 and above, including the latest PostgreSQL 18, and runs on Linux, Windows, and macOS.

Query Tool and SQL Editor

pgAdmin’s query tool is a full-featured SQL editor with syntax highlighting, code completion, and query history. It supports multiple query tabs, result set filtering and sorting, and graphical explain plan visualisation. The built-in graphical query builder lets you construct queries visually without writing SQL.

• Syntax highlighting: Colour-coded SQL with configurable themes
• Auto-complete: Context-aware suggestion for tables, columns, and functions
• Explain visualisation: Graphical execution plan with cost analysis
• Data export: Export results to CSV, JSON, XML, and other formats

Server Administration

pgAdmin provides comprehensive tools for managing PostgreSQL servers, databases, and user accounts. You can create and configure databases, manage tablespaces, set configuration parameters, and monitor server activity in real-time. The dashboard gives you an at-a-glance view of server health and performance metrics.

• Connection management: Manage multiple servers with SSL/TLS support
• Role and privilege management: Create users, groups, and set granular permissions
• Configuration editor: Browse and modify postgresql.conf settings
• Dashboard: Real-time graphs of server activity, connections, and transactions

Schema Management

pgAdmin offers a tree-based browser that lets you navigate database objects including tables, views, functions, triggers, and indexes. The visual designer supports creating and modifying objects without writing DDL, while also showing the SQL that will be executed for learning purposes.

• Object browser: Hierarchical tree view of all database objects
• Visual table designer: Point-and-click table creation and alteration
• ERD tool: Visual entity-relationship diagrams from existing schemas
• Reverse engineering: Generate diagrams and documentation from live databases
