Agreed on using -T.

I tried Jason's example on my server and got an error, so I don't want
to trade one error example for another:

    $ createdb -p 5432 -h localhost -E LATIN1 -T template0 -e demo
    CREATE DATABASE demo ENCODING 'LATIN1' TEMPLATE template0;
    createdb: database creation failed: ERROR:  encoding "LATIN1" does not match locale "en_US.UTF-8"
    DETAIL:  The chosen LC_CTYPE setting requires encoding "UTF8".

I went with the template0 example, attached, and applied it to head.
