Re: what's going on...

You need to escape single quotes "'" in plpgsql functions.  The
correct function should look like this:

CREATE FUNCTION analizuj_pomiary() RETURNS bool AS '
DECLARE pomiary RECORD;
BEGIN
     FOR pomiary IN SELECT * FROM brewan_pomiar LOOP

       IF substr(pomiary.datetime,1,10)=to_char(now(),''mm/dd/yyyy'')
       THEN                                            ^           ^
          INSERT INTO TESTOWA                          |           |
          VALUES (                                     |           |
         analizuj_flow(                                |           |
         pomiary.ipRouter,                             |           |
         pomiary.source_ip,                            +-----+-----+
         pomiary.dest_ip,                                    |
         pomiary.bytes,                                      |
         pomiary.datetime)                                   |
         );                        Look at US!!
       END IF;

     END LOOP;
 RETURN true;
END; ' LANGUAGE 'plpgsql';
