actually a user was looking for a database modeling tool at the postgresql mailinglist. As I do use a piece of paper for my db modeling and having used DbDesigner during my time using MySQL and Windows, I thought it would be a good chance to have a look at some tools. Actually two have been supposed by the list members.
Power* Architect (thanks to Thomas Kellerer for the tip)
This is a data modeling and profiling tool. It supports not just PostgreSQL but also many other DBMS. The connection to the database is handled by a JDBC driver. It’s avilable for MAC OS X, Windows and Linux and it’s open source (GPL v 3).
Here are some more features (copied from the page below):
- Connects to multiple source databases concurrently
- Compares data models & database structures and identifies discrepancies
- Drag-and-drop source tables & columns into the playpen
- Remembers the origin of each column
- Generates source-to-target visual Mapping Reports
- Forward-engineers to PostgreSQL, Oracle, MS SQL Server & more
- Saves source data structure snapshots in the project, so you can work remotely
- All project data is stored in an easy-to-parse XML format
- OLAP schema modeling: Cubes, Measures, Dimensions, Hierarchies & Levels
