The option (sorry, I know this may look sarcastic, but I donβt think so) is post-buffering, but before setting it up, make sure that the proxy server uses a post-unbuffered web server (for example, apache). If not, you can ignore this message.
If you use Nginx with proxy_pass or uwsgi_pass and obviously not proxy_request_buffering off or uwsgi_request_buffering off respectively, you can safely ignore this warning, as query buffering is enabled by default starting from version 1.7.11. See the documentation for proxy_buffering and uwsgi_request_buffering .
