PostgreSQL ER Diagrams, Schema Design, and SQL Client

Connect DbSchema to PostgreSQL and turn the live schema into an editable visual model: explore relationships in interactive ER diagrams, plan changes on the canvas, and generate reviewed SQL scripts for deployment.

The workflow is designed for relational modeling, migration planning, and SQL-first collaboration — keep an offline model in Git, collaborate across teams, and publish documentation that developers, analysts, and stakeholders can navigate in minutes.

1
Install in minutes

Download the installer for Windows, macOS, or Linux and launch DbSchema. No signup required.

2
Connect to PostgreSQL or open a sample

Reverse engineer an existing PostgreSQL database or open a sample model to explore tables, relationships, and indexes.

3
Design, document, and deploy

Edit schema visually, generate documentation, and prepare reviewed migration scripts for safer releases.

PostgreSQL Database Design and Documentation in One Tool

DbSchema helps PostgreSQL teams move faster from schema understanding to safe changes. Reverse engineer live databases into interactive ER diagrams, explore relationships visually, write SQL, and publish documentation your team can actually use. Keep one design model in Git and deploy reviewed changes across development, staging, and production.

Reverse Engineer PostgreSQL Schemas into ER Diagrams

Connect to PostgreSQL and DbSchema imports tables, views, materialized views, indexes, and foreign keys into a navigable visual model. PostgreSQL-specific structures such as JSONB columns, arrays, and advanced constraints remain visible in context so you can understand complex schemas faster.

Design Changes Visually, Generate SQL Safely

Add columns, adjust constraints, or define new relationships directly on the diagram. DbSchema generates the SQL DDL for review before execution, so teams can validate schema changes before they reach production. Compare environments and create migration scripts with a predictable, review-friendly workflow.

Query PostgreSQL Visually or with SQL

Use the visual query builder to create joins and filters quickly, then switch to SQL editor mode any time for full control. This is ideal for mixed teams where analysts prefer visual exploration and developers want direct SQL execution.

Version Schema Changes with Git

Store the DbSchema model file in your repository and review schema evolution with the same Git process used for application code. Teams can collaborate on structural changes, keep a history of decisions, and roll back with confidence.

Versioning PostgreSQL schema with Git in DbSchema

Connect DbSchema to PostgreSQL in Minutes

  1. Download DbSchema for Windows, macOS, or Linux and open it — no signup.
  2. Create a connection and pick PostgreSQL; DbSchema can download the PostgreSQL JDBC driver automatically on first connect.
  3. Fill in host, database, and credentials. The default port is 5432 and the JDBC URL format is jdbc:postgresql://host:5432/dbname.
  4. Connect — tables, views, and foreign keys are imported into an editable ER diagram.

SSL is supported natively, and standard PostgreSQL access configuration in postgresql.conf and pg_hba.conf works as expected. The same steps apply to PostgreSQL-compatible services such as Neon, Supabase, and Aurora PostgreSQL.

DbSchema vs pgAdmin

pgAdmin is the community's standard administration tool for PostgreSQL and excels at server management. DbSchema approaches PostgreSQL from the design side — diagrams, an offline model, and documentation — and covers the rest of your database estate with the same workflow.

Supported databases 100+ engines, including every major PostgreSQL flavor PostgreSQL family
ER diagrams Interactive diagrams with multiple layouts, saved in the model ERD tool per database
Offline design model in Git Yes — reviewable project file plus Git integration (Pro)

Tutorials and guides

Frequently asked questions

For schema design, ER diagrams, and documentation, yes — DbSchema adds an offline model with Git versioning and interactive HTML docs, while pgAdmin remains the standard for PostgreSQL server administration. Many teams use both.

Yes. DbSchema uses the official PostgreSQL JDBC driver and supports SSL/TLS with standard connection parameters in the JDBC URL.

Yes. Connect to your instance and DbSchema imports tables, views, indexes, and foreign keys into an interactive ER diagram you can edit and document.

Yes. The Community edition is free and includes reverse engineering, interactive ER diagrams, visual table editing, and the SQL editor. Pro features can be evaluated with a 15-day trial.

Port 5432. The JDBC URL format is jdbc:postgresql://host:5432/dbname.

Teams working with PostgreSQL often use these engines too. Explore dedicated guides and JDBC setup for each.
