Dataimport from remote db - Mailing list pgsql-novice

Hello,

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

I tried something like this but maybe there is a better way in doing
such a thing???

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.
