DB Migration DDL generation for UUID type when generating multiple platforms

[rbygrave]

When generating a DB migration targeting multiple platforms ... and using UUID types the generated type of the UUID properties is controlled by the default platform type (rather than each specific platform).

Expected behavior

We expected the appropriate DDL column definition for "logical UUID" types based on the platform. So H2 and Postgres have native UUID type support but MySql, Oracle, Sqlite don't and we would expect VARCHAR(40), VARCHAR2(40) etc or BINARY(16) depending on the ServerConfig DbUuid setting.

Steps to reproduce

    DbMigration dbMigration = new DbMigration();
    dbMigration.addPlatform(DbPlatformName.POSTGRES, "postgres2");
    dbMigration.addPlatform(DbPlatformName.SQLITE, "sqlite2");
    dbMigration.addPlatform(DbPlatformName.ORACLE, "oracle");
    dbMigration.addPlatform(DbPlatformName.ORACLE, "mysql");
    dbMigration.generateMigration();
