I looked at all the patches too. The patch is only 9k lines, not huge.
Other than the locking part, the biggest part of this patch is adjusting
things so that an INSERT can change into an UPDATE. The code that
handles SELECT/INSERT/UPDATE/DELETE is already complex, and this makes
it even more so. I have no idea how we can be sure we have hit every
single case, but I am also unclear how we will _ever_ know we have hit
them all.
We know people want this feature, and this patch seems to be our best
bet to getting it. If we push this off for 9.6, I am not sure what that
buys us.
