Great, thank you for working on this! I'll start with the reason I set the work down before: it did not work well with multiple join keys. That might be fine, but I also started thinking it was specialized enough that I wanted to look into doing it as an extension using the CustomScan mechanism. Do you have any solution to working better with multiple join keys? And do you have thoughts on whether it would be a good candidate for the CustomScan extension mechanism, which would make it easier to experiment with? Regards, Jeff Davis
