As I do all stuff locally I have not configures for necessity of login
username/passwd.
So i assume I can omit it. With psql I don't need one.
"???" means my password I assume...

Well, I have configured it, so I maybe need it?
With psql not, but I have set it. I think it will not be checked from the db.

Why did you make uid="rtest"?
rtest is the name of the database.
I use "oliver" as db-login-name.

With psql I can login.
And I need no passwd.
Maybe it's different for the R-connection, instead of starting psql from the
shell? But I don't think so.
