Generate production-ready PostgreSQL SQL code from your Mermaid ER diagrams in seconds.
How to convert Mermaid ER to PostgreSQL
Converting Mermaid ER diagrams to PostgreSQL is simple with Diagram2Code. Mermaid is a Markdown-inspired diagramming tool that is natively supported by GitHub, GitLab, and Notion. Just paste your Mermaid ER source code into the editor above, and our engine will parse your entities to generate optimized PostgreSQL code.
Why use Diagram2Code for PostgreSQL generation?
Manually writing PostgreSQL DDL from a visual design is time-consuming. Diagram2Code ensures that your database schema perfectly matches your visual ER diagram. The generator also handles COMMENT ON statements for column-level documentation.
Mermaid ER Parsing
Leverage Mermaid's erDiagram syntax to define your data model directly in your documentation.
PostgreSQL Output
PostgreSQL-specific types like JSONB, UUID, and TIMESTAMPTZ.
Technical Mapping
SERIAL primary keys and CREATE TYPE enums.
By using this "diagram 2 code" approach, you eliminate the risk of schema drift and ensure your PostgreSQL implementation is always in sync with your architectural design.
