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.

There is no need to import testutils.unittest instead of simply
unittest. They are simple aliases. Use system unittest to be more
regular, consistent as well as idiomatic with the wider Python
community.
It was registered as side effect of an excessive definition that got
cleaned up in 338dbe70a6.
Looking at other removed redundant type oids, this was the only one
missing from the `string_types` map.
Close#578.
Should close#558, but I'm curious to know if a number is returned
for interval < 1 day too (which wouldn't trigger the overflow, but will
finish parsing with part=0).
(almost... except for micros rounding)
While this is probably an improvement on the previous implementation,
I am largely waving a dead chicken at windows, which keeps failing to
pass the seconds overflow test. If it doesn't pass now either I'll start
blaming Python's timedelta.
Named cursors on old server versions have a different prefetch behaviour.
This has hidden me the supported range of the 24:00 time format.
Let's have another go at full testing...
Avoid creating new a new FixedOffsetTimezone instance if one with the
same offset and name has been created before. This will save memory
when returning many rows containing "timestamp with timezone" columns,
and also improves comparability.
The offset displayed was always positive and somewhat confusing. The
offset displayed now is the offset that the instance was created
with.
Also added some tests for initialisation.
Dropped cyclic import from modules to tests: they were only working
because a second copy of the package was found in the project dir.
Use relative import so that 2to3 can do a good conversion.
Allow the objects to be recognized as the proper type by Postgres in not
strong contexts: problem reported by Peter Eisentraut.
Added tests to check the types are respected in a complete Py -> PG ->
Py roundtrip without context.
coverage for datetime and time strings with and without time zone
information.
* psycopg/typecast_datetime.c (typecast_PYDATETIME_cast): adjust
to handle the changes in typecast_parse_time.
(typecast_PYTIME_cast): add support for time zone aware time
values.
* psycopg/typecast_mxdatetime.c (typecast_MXDATE_cast): make sure
that values with time zones are correctly processed (even though
that means ignoring the time zone value).
(typecast_MXTIME_cast): same here.
* psycopg/typecast.c (typecast_parse_time): Update method to parse
second resolution timezone offsets.
negative timezone offsets with a non-zero minutes field.
* tests/test_dates.py (DatetimeTests): Add tests for time zone
parsing. The test for HH:MM:SS time zones is disabled because we
don't currently support it.
Currently the second fails for negative offsets due to bugs in the
parser, and the third fails because it doesn't even try to parse second
offset values (as Python doesn't either).
* tests/*.py: use the DSN constructed in tests/__init__.py.
* tests/__init__.py: allow setting the host, port and user for the
DSN used by the tests through the environment.
return value for partially parsed time values.
* psycopg/typecast_mxdatetime.c (typecast_MXDATE_cast): return
NULL after setting DataError. Also, don't treat it as an error if
typecast_parse_time() returns 0 (as might happen if the remainder
of the string is " BC").
* psycopg/typecast_datetime.c (typecast_PYDATE_cast): return NULL
after setting DataError.
(typecast_PYDATETIME_cast): same here.
(typecast_PYTIME_cast): same here.
* tests/test_dates.py
(CommonDatetimeTestsMixin.test_parse_incomplete_date): test that
parsing incomplete date values results in DataError.
(CommonDatetimeTestsMixin.test_parse_incomplete_time): same for
times.
(CommonDatetimeTestsMixin.test_parse_incomplete_time): same for
datetimes.
* tests/test_dates.py: add tests for date/time typecasting and
adaption.
* psycopg/adapter_mxdatetime.c (mxdatetime_str): add support for
outputting BC dates (which involves switching them to one-based
dates). Also remove broken handling of microseconds.
* psycopg/typecast.c (typecast_parse_date): if the string ends
with "BC" adjust the year value to be a zero-based BC value as
used by mx.DateTime (datetime doesn't support BC dates).
(typecast_parse_time): ignore ' ', 'B' and 'C' in time strings
rather than treating them as part of the seconds part of the time.
