Issue with --create-database argument

I am trying to run the mbslave init --create-database

The code here: https://github.com/acoustid/mbdata/blob/ea0e7e2af55096b221b54f3c1e59154f9c03583b/mbdata/replication.py#L584 seems to try to connect to the "musicbrainz" database before it is created, and I get the error FATAL: database "musicbrainz" does not exist:
