They can be valid chars in Python 3. Or maybe not? In which case Python
will throw an exception, but that's fine.
Fix regression introduced fixing #211
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.
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 docs don't need to describe what will happen on Python versions
before 2.6 as they are unsupported by psycopg2.
Should have been included in commit
d58844e548, but was missed.
The decimal module is available on all Python versions supported by
psycopg2. It has been available since Python 2.4. No need to catch an
ImportError.
https://docs.python.org/2/library/decimal.html
All Python versions supported by psycopg2 have the json module. It was
added in Python 2.6. Can remove checks for availability, slightly
simplifying the code.
namedtuple is available on all Python versions supported by psycopg2. It
was first introduced in Python 2.6. Can remove all workarounds and
special documentation.
The syntax "except Exception, exc:" is deprecated. All Python versions
supported by psycopg2 support the newer, modern syntax. Forward
compatible with future Python versions.
I'll be honest: I lucked out, I didn't think about this combination. But
maybe sheer luck, maybe using common code paths, it just works. Let's
make it stays so.
