+Subject: Only remove init connections to the database on server shutdown.
+
+Summary:
+With MariaDB 10.2 libmysqlclient was replaced with libmariadb that
+changed how establishing database connections behaves. The MySQL
+QSQL driver calls mysql_server_end() on QSqlDatabase::removeDatabase()
+if the overall connection count dropped to 0 (which it does when
+the init connection is removed).
+A future QSqlDatabase:addDatabase() would call mysql_server_init()
+again, but this no longer works with libmariadb as that one only
+allows calling mysql_server_init() once. Future calls are simply
+ignored.
+
+In order to prevent this from happening we have to keep the
+init connection open until the server shuts down, so the connection
+count only drops to 0 at shutdown and mysql_server_end() isn't
+called before.
+
+This is a workaround for QTBUG-63108
