Agreed. Many people on hackers don't actually deal with production
systems, so it's easy to look at things from an academic standpoint
and not a practical one. This is generally a Good Thing (I think
MySQL is an example of what happens when you don't do that), but it
does need to be balanced by real-world needs. And not all of those
needs are always well represented on the lists.
In this case, I have bulk-load code that could certainly use MERGE.
It's not that hard to write code that will handle this in a way
that's not safe from race conditions, so it's unlikely that we'll see
that many requests, but that doesn't mean a fast MERGE wouldn't be
useful. It certainly would have saved me some effort, and it would
probably out-perform the current code.
