Your best bet is to recreate the database. Start with an database that has all
the tables already emptied out, then make a copy of it. Then drop and
recreate your database at will using the copy as a template. So, if your
datbase was named "alpha", you would do (one time only):

(truncate all tables, get the alpha database in a clean state)
CREATE DATABASE alpha_template TEMPLATE alpha;

Then, every time you want to create a clean copy, do:

DROP DATABASE alpha;
CREATE DATABASE alpha TEMPLATE alpha_template;
