Just a brief note on this:

I originally introduced this just because Qunar.com (the biggest
air-ticket search engine here in China) is storing (small) images into
their PostgreSQL databases, and they'd like to serve out the images
directly to the web browsers, and without introducing any extra middle
layers to maximize speed.

This allows simple code branches by using nginx's if mechanism. And
yeah, nginx's "if" is evil but it can make simple things easy. It's
recommended to use ngx_lua's set_by_lua and other stuffs to do
complicated code branching though :)
