"createdb" is a shell command; you'd issue that to your shell not to psql.
The equivalent thing to do in psql would be

create database mydb;

(don't forget the semicolon). Also, once you'd created it, the
way to switch to it within a psql session would be

\c mydb

While we're here, notice the subtle changes in psql's command prompt
--- that indicates that it thinks you're continuing a multiline command.
That's why nothing seems to be happening. If you'd typed a semicolon
to end the command, you'd have gotten a syntax error of one sort or
another.
