Because of that I actually had to manually create each table, row, and constraint in the diagram and it took me hours. Generate Your Relational Database Schema. When I initially tried to create an ERD using pgAdmin 4 I clicked on the “New ERD Project” option in the Tools dropdown and it gave me a blank grid to work off of.
