php-src/ext/mysqlnd/mysqlnd_statistics.c
Kamil Tekiela 132d499424 Drop mysqlnd statistics triggers 
This functionality is not used productively in PHP and it's not used in
any of the extensions to my knowledge. Since it looks like this functionality
isn't required by anyone, let's clean up mysqlnd and drop it.
