Tom Lane 307c78852f Rethink representation of PathTargets. ... In commit 19a541143a I did not make PathTarget a subtype of Node, and embedded a RelOptInfo's reltarget directly into it rather than having a separately-allocated Node. In hindsight that was misguided micro-optimization, enabled by the fact that at that point we didn't have any Paths with custom PathTargets. Now that PathTarget processing has been fleshed out some more, it's easier to see that it's better to have PathTarget as an indepedent Node type, even if it does cost us one more palloc to create a RelOptInfo. So change it while we still can. This commit just changes the representation, without doing anything more interesting than that.		2016-03-14 16:59:59 -04:00
