Hello,

i have several machines having the same database layout. Now i want
import data from a remote machine.

I tried something like this:

CREATE OR REPLACE FUNCTION import_sc(text)
RETURNS int4 AS $$
DECLARE
v_host ALIAS FOR $1;
v_return int4;
v_constr text;
v_config record;
temp record;
BEGIN
v_constr := 'hostaddr=' || v_host || ' dbname=config
user=user password=pass';

-- connect to remote database
PERFORM 'SELECT dblink_connect(''con'', v_constr);';
RAISE NOTICE 'connected';

FOR v_config in (SELECT * from dblink('''con''',
'SELECT * from config ') AS
hc(id character(36), name text))
LOOP
INSERT INTO config (id, name) values
(v_config.id, v_config.name);
END LOOP;

PERFORM 'SELECT dblink_disconnect (''con'');';

v_return := 4;
RETURN v_return;

END;
$$ LANGUAGE 'plpgsql';

But now I get:
NOTICE: connected

ERROR: could not establish connection
DETAIL: missing "=" after "'con'" in connection info string

CONTEXT: PL/pgSQL function "import_sc" line 13 at FOR over SELECT rows

********** Fehler **********

ERROR: could not establish connection
SQL Status:08001
Detail:missing "=" after "'con'" in connection info string
Kontext:PL/pgSQL function "import_sc" line 13 at FOR over SELECT rows

What does that mean?

Thank you very much.
Tobias
