Hey Hannu,

I took the above for a spin and generally it all worked well and I do
think it is a nice addition. Attached v4 patch basically combines v3
01 and 02 patches into one (you need both or the build fails on the
docs, so...), along with the following changes:
- whitespace and typo fixes in pgbench.c
- wordsmithing the caution notification, clean up --no-functions doc
- document the new Yy options alongside other -I options.

On that last item, I did notice that there is a potential backwards
compatibility issue, which is that existing scripts that are reliant
on functions existing will need to be updated to include "y", but that
feels pretty niche, so I am not personally worried about it.
