RELEASE: psycopg 2.4.4

Hi *,

after a short discussion on this list we decided to change the
definitions of isolation levels to make sure old code using numeric
constants (both psycopg1 and psycopg2) continue to works. Daniele also
slipped in some other changes, detailed in the NEWS file, below (oh! oh!
oh!).

What's new in psycopg 2.4.4
---------------------------

- 'register_composite()' also works with the types implicitly defined
after a table row, not only with the ones created by 'CREATE TYPE'.
- Values for the isolation level symbolic constants restored to what
they were before release 2.4.2 to avoid breaking apps using the
values instead of the constants.
- Named DictCursor/RealDictCursor honour itersize (ticket #80).
- Fixed rollback on error on Zope (ticket #73).
- Raise 'DatabaseError' instead of 'Error' with empty libpq errors,
consistently with other disconnection-related errors: regression
introduced in release 2.4.1 (ticket #82).

Have fun,
federico
