How to get ERD diagram for an existing database?

Question

I have a PostgreSQL database. I want to get its ERD. How can I do so?

Answer 1

You can use dbeaver to do this. It allows you to export the ER diagram as png/svg etc.

DBeaver - https://dbeaver.io/

Double click on a schema (eg, Schemas->public->Tables) and open the "ER Diagram" tab (next to "Properties" tab)
