This replxx object is pretty heavy and in debug build may slow down [1]
(although I cannot confirm 0.5s delay for each query in debug build) the
client and besides it is not required since ClickHouse-Extras/replxx#10,
which changes the behaviour of history_save(), and now it will not
update current session anymore, only save the history to the disk.

The my_bool type no longer exists, and people may have been using it in their own code since some mysql.h functions have been returning that. The recommended fix is to use bool or int, which will work both in 8.0 and older versions.

By default replxx reload history from the file in
replxx::Replxx::history_save(), and this will overlaps current session
history with the history from other sessions, and this does not looks a
great idea (bash and other interpreters don't do this).
So to avoid this, use separate replxx::Replxx instance.
