Use of %ROWTYPE in plpgsql function declarations

FYI, FWIW.

Speaking of documentation, it's none too clear that
%ROWTYPE does not seem to work when declaring plpgsql
functions.  (pg 8.0.3  I looked at the release notes
and didn't see anything fixed in newer versions.)

So, either the docs are broken, postgres is broken, or
I'm not reading things right/understanding.  (Or maybe
declaring arguments is new enough that it just does not
work yet.)

babase_copy=# create temp table bar (id int, logic boolean);
CREATE TABLE
babase_copy=# create function baz (arg bar%ROWTYPE) returns void
language 'plpgsql' as $$ begin  return; end; $$;
ERROR:  syntax error at or near "%" at character 29
LINE 1: create function baz (arg bar%ROWTYPE) returns void language ...
                                     ^
babase_copy=# create function baz (arg bar) returns void language
'plpgsql' as $$ begin  return ; end ; $$;
CREATE FUNCTION
