    Description

      Doing the following will trigger an error:

      CREATE TABLE test.tmp3
      		 
      (t TINYTEXT)
      		 
      ENGINE=COLUMNSTORE;
      		 
       
      		 
      ALTER TABLE test.tmp3 CHANGE COLUMN t t2 TINYTEXT;

      The error is:
      ERROR 1815 (HY000): Internal error: CAL0001: Alter table Failed: Changing the datatype of a column is not supported

      The cause is typesAreSame() in ddlpackageproc/altertableprocessor.cpp doesn't check for all the TEXT types and fails on the ones it does catch.
