Right.

That's reasonable.

But it's not very clear to me how we could make this case scriptable,
and it would probably not be much different from just using the
proposed option and then running the script afterwards yourself via
psql. The thing about -N and -S is that those scripts are being run
repeatedly, so pgbench has to be involved. If you just want to create
different/extra indexes, you can do that yourself.
