Awesome, I'll try to take a look over the weekend. Looks like you beat 
me to writing an example using $your_favourite_async_library ;)

Skimming over the patches I have a question: is it really necessary to 
add the callback feature into the C library? AFAICS the callback is 
executed on asynchronous cursors everytime there is a execute() attempt. 
Couldn't you just write a Python psycopg2.extensions.cursor subclass 
that overrides execute() by calling that callback?

Cheers,
