Excellent!  Thanks so much.

If I have this:

CREATE OR REPLACE VIEW Link.Foo AS

password=secret',
     'select * from Foo') as ...

Then it works.  However, if I do:

CREATE OR REPLACE VIEW Link.Foo AS
   select * from dblink(

     'hostaddr=db.domain.com <http://db.domain.com> dbname=KitchenPC

user=Website password=secret',
     'select * from Foo') as ...

Then I get:

ERROR:  could not establish connection
DETAIL:  could not translate host name "db.domain.com

<http://db.domain.com>" to address: Unknown host

However, from a command prompt I can ping db.domain.com

<http://db.domain.com> and get 123.123.123.123.

Does dblink just not support DNS resolution?  I really don't want to
hard code IP addresses in my scripts.  Thanks!

See below for explanation of hostaddr and host. Short version, you are looking for host:
