fields in JoinPaths --- turns out that we do need that after all :-(. Also, rearrange planner so that only one RelOptInfo is created for a particular set of joined base relations, no matter how many different subsets of relations it can be created from. This saves memory and processing time compared to the old method of making a bunch of RelOptInfos and then removing the duplicates. Clean up the jointree iteration logic; not sure if it's better, but I sure find it more readable and plausible now, particularly for the case of 'bushy plans'. |
