Answer 1

1. character varying[] needs to be replaced with more compliant with the SQL Standard character varying array (it isn't fully compliant, but H2 also doesn't require length for varchar data type).
2. integer primary key generated always as identity needs to be replaced with standard-compliant integer generated always as identity primary key .
