Introduction

What is `python3-psycogreen`

The psycogreen package enables psycopg2 to work with co-routine libraries, using asynchronous calls internally but offering a blocking interface so that regular code can run unmodified. Psycopg offers co-routines support since release 2.2. Because the main module is a C extension it cannot be monkey-patched to become co-routine-friendly. Instead it exposes a hook that co-routine libraries can use to install a function integrating with their event scheduler. Psycopg will call the function whenever it executes a libpq call that may block. Psycogreen is a collection of “wait callbacks” useful to integrate Psycopg with different co-routine libraries.
