>
> Table volume has an important role in query planning. Tajo's query optimizer
> makes many decisions based on table volume, because it is currently the only
> available statistics.
> However, PgSQLTablespace doesn't support getTableVolume() method, so our plan
> is not good when the query involves any pgsql tables.
