If you are only using a single schema in your database, you could create an empty database with all your tables that you then use as the template database when creating a new one:
Then each time you want to reset your schema (=database) you do a
drop database real_database;
create database real_database template template_database;
Then you don't need to adjust your "reset" script if your database changes (you only maintain the template database using your SQL scripts)
