Memory statistics are not available on a per connection basis but only globally. We need to update
the documentation.
rows_fetched_from_client_normal_buffered are also only incremented on a global level not on a per
connection basis. This should be a bug, leaving it to Andrey to decide and fix.

Description:
------------
mysqli_get_connection_stats() doesn't seem to work, but mysqli_get_client_stats()
does.
mysqli_get_connection_stats() gives nearly no information at all, big part of
fields it returns are '0' valued
Test script:
---------------
ini_set('mysqlnd.collect_statistics', 1);
ini_set('mysqlnd.collect_memory_statistics', 1);
$db = mysqli_connect('server', 'user', 'secret', 'mydb');
$result = mysqli_query($db,"SELECT user_id FROM users LIMIT 5");
mysqli_data_seek($result, 5);
$data = mysqli_fetch_row($result);
var_dump(mysqli_get_connection_stats($db));
Expected result:
----------------
I expect the keys "mem_***" to contain non null values
"rows_fetched_from_client_normal_buffered" should be 1 as I fetch one value from
a buffered non prepared dataset
Actual result:
--------------
