Tom Lane	e6381966c1	Major planner/optimizer revision: get rid of PathOrder node type, ... store all ordering information in pathkeys lists (which are now lists of lists of PathKeyItem nodes, not just lists of lists of vars). This was a big win --- the code is smaller and IMHO more understandable than it was, even though it handles more cases. I believe the node changes will not force an initdb for anyone; planner nodes don't show up in stored rules.	1999-08-16 02:17:58 +00:00
