pgAdmin 4's Query Tool in version 9.13 delivers a comprehensive SQL development environment with AI-powered features and enhanced workspace layouts. The tool provides SQL editors, result set management, and execution plan visualization through an intuitive dual-panel interface. Users can execute ad-hoc queries, edit updatable result sets, and export data to CSV formats.

A standout addition is the AI Assistant tab, which generates SQL queries from natural language descriptions when configured with an AI provider. The workspace layout offers a distraction-free environment where all Query Tool and View/Edit Data tabs open within a dedicated workspace. Users can connect to ad-hoc servers through a streamlined connection interface that accepts server details, database names, and authentication credentials.

The tool includes a Query History panel that tracks the last 20 queries per database by default, displaying execution times, row counts, and server messages. Features like syntax coloring, autocompletion (activated with Control+Space), and drag-and-drop object insertion streamline development. The SQL editor supports partial execution of highlighted code sections and cursor-based query detection. With its combination of traditional database tools and modern AI capabilities, pgAdmin 9.13's Query Tool represents a significant evolution in database administration interfaces.
