Fixed for 1.1.
Steps to reproduce:

set global slow_query_log=1;

set slow_query_log=1;

select l_orderkey,l_linenumber,l_shipmode,l_shipinstruct,l_shipinstruct from lineitem order by 1,2;

update lineitem set l_linenumber  where l_shipinstruct='COLLECT COD';

After that one consults /usr/local/mariadb/columnstore/mysql/db/$hostname-slow.log for slow query entries.

Please review.
