org.hibernate.type.TextType a Oracle

Toto fungovalo pro mě. Rozšířený PostgreSQL81Dialect takto:

public class MyPostgreSQL81Dialect extends PostgreSQL81Dialect
{

  @Override
  public SqlTypeDescriptor getSqlTypeDescriptorOverride(int sqlCode)
  {
    SqlTypeDescriptor descriptor;
    switch (sqlCode)
    {
      case Types.CLOB:
      {
        descriptor = LongVarcharTypeDescriptor.INSTANCE;
        break;
      }
      default:
      {
        descriptor = super.getSqlTypeDescriptorOverride(sqlCode);
        break;
      }
    }  
    return descriptor;
  }

}
