    The Entity-Relationship Diagram (ERD) tool in pgAdmin is a powerful database design utility that provides a graphical representation of database tables, their columns, and relationships. It is particularly useful for visualizing, designing, and maintaining databases.

    Key Features of the ERD Tool

    The ERD tool allows users to design and visualize database structures. You can create new tables, define relationships, and even generate SQL scripts directly from the diagram. It supports features like:

    • Auto-alignment for cleaner visualization.

    • Drag-and-drop functionality to add tables from the object explorer.

    • Export options to save diagrams as images or generate SQL scripts.

    • Customizable depth for traversing relationships between tables.
