Tom Lane 8dcf18414b Fix cost_nestloop and cost_hashjoin to model the behavior of semi and anti ... joins a bit better, ie, understand the differing cost functions for matched and unmatched outer tuples. There is more that could be done in cost_hashjoin but this already helps a great deal. Per discussions with Robert Haas.		2009-05-09 22:51:41 +00:00
