This includes the patches to get from the initial version of the database to its current state - for the purpose of documentation. Beware, if you already have an existing database, running this code will likely result in an error and/or lead to some minor data loss. You need to follow these steps to fix your DB: 1. delete all *.sql files from unwind/sql/ 2. remove the .disabled suffix from unwind/sql/00000001-fix-db.sql.disabled 3. start the application once, this will fix up the database 4. revert all changes to unwind/sql/ – or leave it, it doesn't matter.
