      Description

      There are number of regression tests that starts failing after MCOL-4464. Here is how the bug looks like:

      MariaDB [test]> create table t1 (d decimal(18,2), c char(1)) engine=columnstore;
      Query OK, 0 rows affected (0.412 sec)
       
      MariaDB [test]> insert into t1 values (42, 'z');
      Query OK, 1 row affected (0.206 sec)
       
      MariaDB [test]> select d & c from t1;
      ERROR 1815 (HY000): Internal error: st: 0 TupleBPS::receiveMultiPrimitiveMessages() caught  an exception originally thrown by PrimProc: 
      

      The implementation calls dataconvert code that throws trying to cast from the string 'z' into an internal decimal representation. Here is the call stack of the exception thrown.
