No, and it would be a really bad idea if you could, as the password
would be exposed to everyone else on the machine (via "ps") while
createuser runs.
There are various ways to do this securely, but putting the password
on a program's command line isn't one of them. I'd suggest looking
at how psql's \password command does it.
