PostgreSQL Version:
PostgreSQL 7.3.4 on i386-redhat-linux-gnu, compiled by GCC 
i386-redhat-linux-gcc (GCC) 3.2.2 20030222 (Red Hat Linux 3.2.2-5)

I'm trying to pass a row into a function and cannot get it to work. The code 
doing the calling is (logs_preupd_func):
    test    RECORD;

    SELECT INTO test * FROM logs WHERE order_num = new.order_num;
    PERFORM valid_event_time (test);

The defintition for valid_event_time ():

CREATE OR REPLACE FUNCTION valid_event_time (logs)
    RETURNS text AS '
I get the following error:
WARNING:  Error occurred while executing PL/pgSQL function logs_preupd_func
WARNING:  line 131 at assignment
ERROR:  Attribute "test" not found

This example in the docs indicates that this can be done as in:
CREATE FUNCTION use_two_tables(tablename) RETURNS TEXT AS '
    in_t ALIAS FOR $1;
    use_t table2name%ROWTYPE;
    SELECT * INTO use_t FROM table2name WHERE ... ;
    RETURN in_t.f1 || use_t.f3 || in_t.f5 || use_t.f7;
' LANGUAGE 'plpgsql';

Can anybody show me the error of my ways?
