title: liquibase generates wrong uppercase characters when generating the sql
body: <p>Im working with jhipster and it uses liquibase to manage tables. But when it generates the sql query it messes up the characters. it turns "int" to "İNT" not "INT" and other "i" characters to "İ" (turkish character for uppercase i) so postgresql doesnt accept those. How do I make liquibase use english locale instead of turkish locale for uppercase conversion?</p>
