As I understand it, the approach I've taken here can't be backpatched because it changes the aminsert_function interface (it needs the current snapshot when inserting), so I was proposing this as an improvement for 9.6. I guess there are other way to get the right snapshot into btinsert (and thence _bt_check_unique), but I didn't think it would be very classy to introduce a 'current snapshot' global variable to smuggle it in. > Let's set good standards for responsiveness and correctness. > > > I'd also like to see some theory in comments and an explanation of why we're > doing this (code).
