To clarify: there are good reasons not to like what Oracle calls hints. On the other hand, the concept of hints that tell the planner what selectivity or rowcount to expect (as opposed to trying to control the plan directly) has met with generally more positive reviews. There's no specific design yet, and certainly no implementation roadmap, but I'd not be surprised if we get something like that a few years down the road. regards, tom lane -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
