> Currently, UUID columns can be selected or even filtered if a table 
> containing such a column is created not by the Calcite-based SQL engine (for 
> example via cache API using {{@QuerySqlField}} field annotation).
> But we cannot use it in DDL:
> {noformat}
> CREATE TABLE t (id UUID)
> {noformat}
> Or cast:
> {noformat}
> SELECT CAST(id AS UUID)
> {noformat}
