Evidently you are neglecting to check for failure of the dropdb step.
Perhaps something like

    while ! dropdb active_demo; do
        sleep 10
    done
    createdb active_demo
    /usr/bin/psql active_demo < demo_model.sql > /dev/null

This kinda begs the whole question of interlocking though; won't people
see funny behavior when you do this?
