I think it's at the very least two months of serious development work to get it into a state ready for submission. And a good chunk of that not even sketched out. Replacing the hashtable is the easy part, the memory management (Complicated due to lock-freeness. I'm thinking of using a variant of epoch based reclamation) isn't really there, the management of shared "open relations" state are the hard parts... So yes, I could use help on it, but it'll be a lot of actual design and investigatory work. Greetings, Andres Freund
