Enable Enterprise Geodatabase issue

Question

I am new to the Postgresql and quite familiar with ArcGIS Pro. I create a database usa in pgadmin 4 (13.6 version) and import the data into usa database. Then I created login role sde and password in pgadmin and sde schema in usa. Then I went to ArcGIS Pro (2.9) Catalog and right click on the Databases and click new Database connection and configure the connection below. It is successfully to establish the connection. See below.

Then I need to enable the enterprise geodatabse, but get an error message below.

It seems that there are multiple problems in there. Anyone who can help me to figure out the problem and how to solve these issues? Your help will be highly appreciated.

You are correct. The port number does not work properly. The localhost worked fine.

I used the "create enterprise geodatabase" once and were able to connect the exsiting database in pgadmin. I also changed the instance to localhost and used a new computer. It worked without any errors. Thank you so much for help.

I will use it for teaching students. The first part I will do is to import non-spatial data and do the non-spatial query in pgadmin. Then, I will show them how to connect the existing non-spatial data in pgadmin with ArcGIS Pro and do spatial queries (I know that pgadmin usually connects with qgis, but most of my students are more familar with ArcGIS pro. So, I will use the ArcGIS pro connect with pgadmin). That is why I did not create an enterprise geodatabase at the first place. Anyway, the errors are gone after I changed to a new computer. I guess it is because something is missing my laptop. I also changed the instance to localhost. It worked.
