I just now tried creating a second server with pgadminIII. I am confused as to why one would have more than one server. There does not seem to be any way to "switch" from one server to another, or to log into one particular server (and not the other), or to create tables specifically for one server. I find the concept rather confusing. I understand that if I limit myself to one server, then I may define different database, and log to a particular database, and see only the tables in that database. Any explanation regarding more than one server will be appreciated. Thanks.
