The only important command in db_remove.sql is 'drop database alfresco;'. The db_setup.sql script just recreates it (empty) and adds the alfresco user. The first time you start Alfresco it creates the tables. The other important step is to remove all the content files and lucene indexes - so the other thing the db_remove.bat script does is trash the alf_data folder and contents.
