Research direction

Start with the mysqltest case mview.create_mview_with_column_store_mysql and run it against the seekdb binary using the provided startup command. Compare its EXPLAIN output, especially the Outputs & filters line, with the expected result; the work is complete when that line includes rowset=16 again.
