Try running the query with literals (especially for v_journal_code).
You may have run the query with a value that represents enough rows
where the optimizer is using a plan that was good for that value, but
not all the others.



Also, is pga_aggregate_target set?  The optimizer may determine it has
enough memory to create the hash table rather than using nested loops.

Steve
