Hmm... there's actually no mention of that in the docs for such tools:
http://www.postgresql.org/docs/9.0/static/app-createdb.html

There's also little mention of this "administrative" database in the
docs beyond saying it's merely a copy of template1 used as a default
database for users and applications to connect to.

I also notice there's no choice but to use the "postgres" database
with these tools.  Shouldn't we have an option that allows us to
specify an alternative database?

e.g.

createdb -d alternativedb newdb
