I'm not sure we should add micro-optimized versions of the existing scripts
to pgbench.  Your point about demonstrating the benefits of server-side
functions seems reasonable, but it also feels a bit like artifically
improving pgbench numbers.  I think I'd rather see some more variety in the
built-in scripts so that folks can more easily test a wider range of common
workloads.  Perhaps this could include a test that is focused on
server-side functions.

In any case, it looks like there is unaddressed feedback for this patch, so
I'm marking it as "waiting on author."
