      Description

      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.
