To create a database, the createdb executable has to connect to the
cluster. A connection is always to some specific database. The
postgres database was added specifically so that such utilities
could make a connection somewhere so they could do their work. If
you drop it, you break those applications.
This is not a bug. The workaround is to not drop the database which
is automatically created on installation.
