How do I specify that a column should be auto-incremented in pgAdmin?

I have started to learn pgAdmin III to manage a PostgreSQL database. But it wasn't an easy to use application.

If I create or have created a table with pgAdmin III, how can I add "auto-increment"-functionality on a column id that has type integer?

This is pretty easy in pgAdmin 4.

First, add a column to your table, then click the little edit icon:

Then go to Constraints and select the Identity type:

Save your table and the column will auto-increment.
