pgAdmin 4版本30及更新版本可以从现有数据库生成ERD。只需右键单击数据库并选择Generate ERD。

Open MySQL Workbench. In the home screen click 'Create EER Model From Existing Database'. We are doing this for the case that we have already made the data base and now we want to make an ER diagram of that database. Then you will see the 'Reverse Engineer Database' dialouge. Here if you are asked for the password, provided the admin password. Do not get confused here with the windows password. Here you need to provide the MySQL admin password. Then click on Next. In the next dialouge box, you'll see that the connection to DBMS is started and schema is revrieved from Database. Go next. Now Select the Schema you created earlier. It is the table you want to create the ER diagram of. Click Next and go to Select Objects menu. Here you can click on 'Show Filter' to use the selected Table Objects in the diagram. You can both add and remove tables here.Then click on Execute.

6.当您点击Next和Finish时，所需的ER图就会出现在屏幕上。

享受。

我使用DrawERD为ERD和DB文件。https://drawerd.com

你可以使用dbeaver来做到这一点。它允许您将ER图导出为png/svg等格式。

双击一个模式(例如，模式->公共->表)并打开“ER图”选项卡(在“属性”选项卡旁边)

Postgresql_autodoc是执行此操作的cli。不做基数，但上面提到的GUI工具都不做。
