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

plperl | t | t | 305959 | PL/Perl
