Description:

psycopg is a PostgreSQL database adapter for the Python programming
language (just like pygresql and popy.) It was written from scratch
with the aim of being very small and fast, and stable as a rock. The
main advantages of psycopg are that it supports the full Python
DBAPI-2.0 and being thread safe at level 2.

This is the first release of the new 2.2 series, supporting not just
one but two different ways of executing asynchronous queries, thanks to
Jan and Daniele (with a little help from me and others, but they did
99% of the work so they deserve their names here in the news.)

psycopg now supports both classic select() loops and "green" coroutine
libraries. It is all in the documentation, so just point your browser to
doc/html/advanced.html.
