I think it's pretty clear that this patch is not Ready for Committer,
because there's no consensus that we want this, and like Tom and
Stephen, I'd argue that there are large parts of it we don't want.
The documentation in the latest patch version mentions XOR and IF
which we definitely don't want because there is no similar thing in
SQL, but in addition to that, I don't think much of an argument has
been made that any of this is actually useful. I'm skeptical about
the notion that giving pgbench a vast repertoire of mathematical
functions is a good idea. What does that actually let us do that is
useful and not possible today?

I'm happy to see pgbench made better in a variety of ways, but I don't
really see why that particular thing is useful. Perhaps I'm just
missing something.
