There is no such edge case. DROP DATABASE has to be issued while
connected to some database, and it won't let you drop the DB you're
connected to.

And CREATE DATABASE has to be issued while connected to some database,
so createdb still has to have a default database to connect to. There
really is no state in Postgres corresponding to "connected but not
connected to any particular database".
It does all hang together. You will need to lose a lot of MySQL
preconceptions along the way, I fear.
