Comment 4 for bug 1840511

Im attaching 2 patches to the case:

- Fixing MySQL building issue (proposed upstream)
- Mitigating GCC 9 issue (reported upstream)

Package maintainer already mitigated both with different patches.

clickhouse (18.16.1+ds-4ubuntu1) eoan; urgency=medium

  * Use gcc-8 to build: see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91500
  * Patch to make it build with mysql

Forcing GCC 8 instead and including mysql.h to a C++ header. These 2 patches could be considered now or in a near future merge, when upstream issues are addressed.
