That won't work:

CREATE FUNCTION logfunc2 (text) RETURNS int4 AS '
    DECLARE
        phrase ALIAS FOR $1;  -- "text" is a reserved word
    BEGIN
        RETURN length (phrase);
    END;
' LANGUAGE 'plpgsql';

testbed# SELECT logfunc2('foobar');
 logfunc2

Maybe plpgsql is not "installed" into template1?

template1# SELECT * FROM pg_language;
 lanname  | lanispl | lanpltrusted | lanplcallfoid | lancompiler
----------+---------+--------------+---------------+-------------
 internal | f       | f            |             0 | n/a
 C        | f       | f            |             0 | /bin/cc
 sql      | f       | f            |             0 | postgres
 plpgsql  | t       | t            |         21024 | PL/pgSQL
