dblink can't query a password with a space

I'm using the following dblink query to connect to another database on
the server. Query itself works fine, however I have the problem that if
the password contains a space character like in "hello world", then
dblink can't connect to that database.

Is there any possibility to get that working with dblink? I have to
dynamically create this view, so I have no choice if a user uses a
password like that. I suppose the same problem occurs when the user name
contains a space character.

CREATE VIEW MyView AS
SELECT * from dblink('host=TestHost port=5432 dbname=TestDB
user=postgres password=hello world','SELECT "Name" FROM "TestTable"') AS
(Name text);

Thank you,
