ANALYZE TABLE for Engine independent status fetches blob/text columns without use

Details

    • 10.1.10, 10.1.11

    Description

      From MDEV-7383, column stats of bob/text columns aren't implemented. They are however still retrieved during the process of ANALYZE TABLE. Removing the retrieval of blob columns during ANALYZE TABLE could potentially save a lot of IO on essentially an IO bound task.
