How do you issue a "CREATE DATABASE" command without being connected to
something?

Ideally, you don't want to be running 8.0 on Windows - it was the first
release on that platform and you'll find a lot of improvements if you
can set aside the time to upgrade to a more recent version. If you are
running 8.0, make sure it's 8.0.19 to get all the latest bug fixes.

If you're not connecting to a database, where do you think the output
goes? Hint - it can't be the database server since you're not connected
to a database.

At a guess, you can't see STDOUT while you're doing this, can you?
Your options are:
1. Create the database and restore directly into it with "-d"
2. Get pg_restore to create the database for you then switch to it,
while connecting with "-d" to an existing database.
3. Have pg_restore output to STDOUT and pipe that to psql with whatever
connection settings you want (which is just duplicating option 2).
