PostgreSQL database adapter for the Python programming language
20d3d0f66d
TypeError is the standard Python error raised in this case:
$ python -c "(lambda a: None)(b=10)"
TypeError: <lambda>() got an unexpected keyword argument 'b'
We only used to raise InterfaceError when connect was used without
any parameter at all, so it's hard to think a program depending on
that design. Furthermore the function has always raised (and still
does) OperationalError too, if the bad argument is detected by the
libpq, and that cannot be changed because we can't tell the
difference from a normal connection error.

psycopg2 - Python-PostgreSQL Database Adapter
********************************************
psycopg2 is a PostgreSQL database adapter for the Python programming
language. psycopg2 was written with the aim of being very small and fast,
and stable as a rock.
psycopg2 is different from the other database adapter because it was
designed for heavily multi-threaded applications that create and destroy
lots of cursors and make a conspicuous number of concurrent INSERTs or
UPDATEs. psycopg2 also provides full asynchronous operations and support
for coroutine libraries.
psycopg2 can compile and run on Linux, FreeBSD, Solaris, MacOS X and
Windows architecture. It supports Python versions from 2.4 onwards and
PostgreSQL versions from 7.4 onwards.
psycopg2 is free software ("free as in freedom" but I like beer too.)
It is licensed under the GNU Lesser General Public License, version 3 or
later plus an exception to allow OpenSSL (libpq) linking; see LICENSE for
more details.
Documentation
-------------
Start by reading the INSTALL file. More information about psycopg2 extensions
to the DBAPI-2.0 is available in the files located in the doc/ direcory.
Example code can be found in the examples/ directory. If you make any changes
to the code make sure to run the unit tests localed in tests/.
Online documentation can be found at: http://initd.org/psycopg/
