The major controversy is the idea of processing multiple sort orderings using a stacked chain of aggregate and sort nodes. I'll follow up shortly with links or a summary of the most significant criticisms; but note that the patch has already been fixed to keep the memory usage bounded regardless of the depth of the chain, so the issue is more about code and design aesthetics than about actually working. There is a description of the current approach in the block comment at the start of executor/nodeAgg.c. A less major issue is whether the introduction of GroupedVar was a good idea; I'm happy with ripping that out again, but if so the code needed to replace it depends on the resolution of the above point, so I've left it as originally submitted pending a decision on that. Greg> What was causing it to take so long. Tom claimed the reviewer/committer spot for himself five or six months ago, and other than the inadequate review and subsequent discussion in December there has been no progress. We posted the latest patch shortly after that (there was some slight delay thanks to the holiday season). Greg> I have time to work on it now Great. I'm actually about to post the latest patch with some tiny updates to match the recent changes in MemoryContextReset, but those are as much cosmetic as anything else (just removing no-longer-needed calls to MemoryContextDeleteChildren). -- Andrew (irc:RhodiumToad)

Any takers? FWIW, "slacking" doesn't mean "I've abandoned Postgres work completely". I'm almost out from under some work-related deadlines (modulo the odd plpgsql performance improvement patch or two ;-)) and expect to get back to your patch and others in the CF before too long. regards, tom lane

I had taken your name off the patch in the CF and was planning to post this request even before I saw rhaas' post, much less your response. It's been almost six months since you claimed the patch, and three months since you said you would "look into" the question of the CTE-based approach per our discussion in December. So frankly I don't feel confident in your "expect ... before too long" ;-) So my request stands. I'll work with whoever gets to it first. -- Andrew (irc:RhodiumToad)
