ERROR: Cannot display a value of type RECORD - Mailing list pgsql-sql

I recieve this error when executing the following function:

select lookup_journal_entries(to_date('20030125','YYYYMMDD'),
to_date('20030125','YYYYMMDD'));

Here is the function itself:

create function lookup_journal_entries(date,date) returns setof journal as '
select * from journal where entry_date >= $1 OR entry_date <= $2'
language 'SQL';

Normally I would expect to see a pointer # returned from the above select
but instead I get this error.
