The idea is to release a package 'psycopg2-binary' to allow installing
binary, and leave the psycopg2 package to be source only, to avoid
pushing the unreliability of the wheel pacakge by default (see issue #543).
Version number bumped to test with new packages.
Make all library code compatible with both Python 2 and Python 3. Helps
move to modern Python idioms. Can now write for Python 3 (with
workarounds for Python 2) instead of the other way around.
In the future, when it is eventually time to drop Python 2, the library
will be in a better position to remove workarounds
Added a very small comparability module compat.py where required. It
includes definitions for:
- text_type -- A type. str on Python 3. unicode on Python 2.
- string_types -- A tuple. Contains only str on Python 3. Contains str &
unicode on Python 2.
For library end users, there is no need to install tests alongside the
package itself. This keeps the tests available for development without
adding extra packages to user's site-packages directory. Reduces the
size of the installed package. Avoids accidental execution of test code
by an installed package.
Per the functions documentation, this argument is not supported on
Python 3. Skip it during tests.
> :param unicode: if `!True`, keys and values returned from the database
> will be `!unicode` instead of `!str`. The option is not available on
> Python 3
Work towards moving tests outside of the installed package.
The tests relied on Python2 relative import semantics. Python3 changed
import semantics to always search sys.path by default. To import using a
relative path it must have a leading dot.
Forward compatible with newer Pythons.
Works towards the goal of moving tests outside of the installed package.

Deprecated in commit b263fbf274 on
2010-01-13. The deprecation warning was first released in version 2.2.2.
The function used to register an alternate type caster for TIMESTAMP
WITH TIME ZONE to deal with historical time zones with seconds in the
UTC offset. These are now correctly handled by the default type caster,
so currently the function doesn't do anything.
The json module is available in all Python versions supported by
psycopg2. No need to check for its presence when executing tests.
Should have been included with d58844e548
but was missed.
Not compatible with Python3. Makes the code more forward compatible with
modern Pythons.
In Python2, it was an alternative syntax for octal.
