-- Gochan master template for new database script
-- Contains macros in the form [curlybrace open]macro text[curlybrace close]
-- Macros are substituted by build_initdb.py to the supported database files. Must not contain extra spaces
-- Versioning numbering goes by whole numbers. Upgrade script migrate existing databases between versions
-- Foreign and unique constraints must be named so they can be dropped. 
-- MySQL requires constraint names to be unique globally, hence the long constraint names.
