Re: dblink inside plpgsql function

I created the following function

CREATE OR REPLACE FUNCTION getReminderServices( varchar ) RETURNS SETOF
reminder_services AS'
DECLARE r reminder_services%ROWTYPE;
BEGIN
SELECT dblink_connect(''dbname=''||$1);
FOR r IN SELECT * FROM dblink(''SELECT * FROM reminder_services'')
AS columns( uid INT,
theme_uid INT,
activity_MT_amount INT,
activity_min_days INT,
activity_max_months INT,
inactivity_days INT,
limit_reminders INT,
limit_months INT,
scanning_time TIMESTAMP WITH TIME ZONE,
reminder_time TIMESTAMP WITH TIME ZONE,
message TEXT)
LOOP
RETURN NEXT r;
END LOOP;
SELECT dblink_disconnect($1);
RETURN;
END;
' LANGUAGE plpgsql;

and I get the same errors. I think it is a problem with the dblink because
the following function it works fine if I call SELECT * FROM getReminders().

CREATE OR REPLACE FUNCTION getReminders() RETURNS SETOF reminder_services
AS'

DECLARE r reminder_services%ROWTYPE;

BEGIN
FOR r IN SELECT * FROM reminder_services
LOOP
RETURN NEXT r;
END LOOP;
RETURN;
END;
' LANGUAGE plpgsql;
