 Luckily, this very thing already exists! To make `psycopg2` stay in Python-land, just add the following in your app startup routines:

 The `psycopg2.extras.wait_select` is just a reference implementation which will replicate the behavior of the default, blocking driver without getting stuck in C-land, and as an added bonus it automatically cancels the SQL query on a `KeyboardInterrupt`. It is of course possible to write your own function to pass into `set_wait_callback()`, which we did when we wrote some more advanced Celery features.
 
-A good starting point to learn about `set_wait_callback` is [https://www.psycopg.org/articles/2014/07/20/cancelling-postgresql-statements-python/](this short article).

We do not use green threads, we run a vanilla setup of Python which is fully synchronous. It is still extremely useful!
