Why is Server Configuration in Pgadmin3 inaccessible for me? My Postgres server is running (localhost:5432), but Tools > Server Configuration is greyed out for me as below. I was attempting to access it to edit/locate my postgres.conf file.
adminpack extension

You need to install the adminpack extension on the server.

CREATE EXTENSION IF NOT EXISTS adminpack


Tips:


Verify the extension is available for installation.SELECT * FROM pg_available_extensions ORDER BY "name" ;
Verify installation.SELECT * FROM pg_extension ORDER BY extname ;
