Hi Tom, Thanks!
So if I want to try out some new join algorithm, or even new type of plan nodes, before I feel the algorithms/nodes are so good that I want to enable the optimizer to consider them as options, is there any better way to experiment with possible new plans?

Only that your code *will* break in each future release, because we have no hesitation about whacking those data structures around ...
