I am trying to visualize tables and their relations using pgAdmin. I have understood that there is a query visualizer tool available for pgAdmin. However, that only is useful if you are dealing with queries. My main goal is to generate a graphical representation of all the tables available in database.
For pgadmin 3 Go to Tools -> Query Tool
Graphical Query Builder is a tab in the Query Tool view.
unfortunately Pgadmin 4 does not have this option.
