Psycopg is a PostgreSQL_ database adapter for the Python_ programming
Psycopg_ is a PostgreSQL_ database adapter for the Python_ programming
language. Its main advantages are that it supports the full Python |DBAPI|_
and it is thread safe (threads can share the connections). It was designed for
heavily multi-threaded applications that create and destroy lots of cursors and
make a conspicuous number of concurrent :sql:`INSERT`\ s or :sql:`UPDATE`\ s.
The psycopg distribution includes ZPsycopgDA, a Zope_ Database Adapter.

Psycopg 2 is an almost complete rewrite of the Psycopg 1.1.x branch. Psycopg 2
features complete libpq_ v3 protocol, |COPY-TO-FROM|__ and full :ref:`object
adaptation <python-types-adaptation>` for all basic Python types: strings (including unicode), ints,
longs, floats, buffers (binary objects), booleans, `mx.DateTime`_ and builtin
datetime types. It also supports unicode queries and Python lists mapped to
PostgreSQL arrays.
Psycopg 2 features complete libpq_ v3 protocol, client-side and
:ref:`server-side <server-side-cursors>` cursors, :ref:`asynchronous
communication <async-support>` and :ref:`notifications <async-notify>`,
|COPY-TO-FROM|__ and a flexible :ref:`objects adaptation system
<python-types-adaptation>`. Many basic Python types are supported
out-of-the-box and mapped to matching PostgreSQL data types, such as strings
(both bytes and Unicode), numbers (ints, longs, floats, decimals), booleans,
datetime objects (both built-in and `mx.DateTime`_), several types of
:ref:`binary objects <adapt-binary>`. Also available are mappings between lists
and PostgreSQL arrays of any supported type, :ref:`dictionaries and PostgreSQL
hstore <adapt-hstore>`, :ref:`tuples/namedtuples and PostgreSQL composite types
<adapt-composite>`.
Psycopg 2 is Unicode and Python 3 friendly.
