Currently, StoreTableExec cannot handle OLTP-like storages. We should
modify StoreTableExec::openNewFile for them. The main objective of
InsertRowExec is to avoid StoreTableExec to be multiple purposed. If we use
StoreTableExec here, StoreTableExec would be more messy to having more
exceptional and intuitive conditions in StoreTableExec::openNewFile().
