I use PostegresQL 9. Is there a free tool to derive UML diagrams from my databases?
Thanks

Export SQL relationship diagram To export a diagram to an image, follow these steps: Right-click the diagram and select Export to Image from the shortcut menu. Specify the target file name and image format. Click the Save button.
You can also import your own database to streamline ERD creation. LucidChart has plenty of collaboration options so you can work on the diagram with your teammates collectively (with features like sticky notes, comments, and mentions).
Convert ER diagram to Class diagramSelect [Convert to Class Diagram] from ER Diagram's pop-up menu in the structure tree. The diagram and all the model elements inside will be converted to a Class diagram and appears in the tree view.
For creating ER diagrams by db reflection, I use: DbVisualizer

It's free.

There's also postgresql_autodoc which can create GraphViz or Dia output. The diagrams will likely require further tweaking, though.

There's a free tool called Dia and a plugin called PostDia. They would do it for you.
Plus:
Requirements for PostDia: python and psycopg2, to install the second one:
pip install psycopg2
