How to create a blank version of a PostgreSQL database

I've been using pgAdmin to create a database and test it. I'm at a point now where I need to install this db on different servers. I've been using pg_dump to do this and I've been able to muddle my way through. But I'm wondering if there's a way to "reset" all the "current" values in any sequence that I have set up? If you have any other general suggestions on how to create "empty" or "blank" databases, can you let me know?
