PostgERD

PostgERD is a CLI tool that connects to a PostgreSQL database using environment variables and generates Entity-Relationship Diagram (ERD) SVG images, or outputs PlantUML and nomnoml files. Version 1.0.7 is latest as of writing, with no regular release cadence. It supports multiple database schemas and relies on dotenv for loading credentials. Differentiators: generates diagrams directly from live PostgreSQL schemas without manual modeling; outputs three formats (SVG, PlantUML, nomnoml). Note that foreign key connections across schemas are only supported in PlantUML output.
