Hello,

I'm using PostgreSQL / SQLAlchemy 0.5.5 and I build my Table objects
using the reflection feature :

{{{
  metadata = schema.MetaData()
  metadata.reflect(bind=_engine)
}}}

I have a table which has a timestamptz column and when I try to insert a
(for example) datetime(2009, 13, 12, 10, 12) in it, it fails with the
following exception : 

<type 'exceptions.TypeError'>: can't compare offset-naive and
offset-aware datetimes

I guess it's because one side has a tzinfo and the other not. When I
look at the documentation the constructor of sqlalchemy.types.DateTime
has a "timezone" parameter which is False by default. However when I
look at the column, timezone is set to True:

Column(u'effective', PGDateTime(timezone=True), table=<content>) 

which is correct.

Any idea how could I resolve this annoying problem ? Is it possible to
set a default timezone in SQLAlchemy, or do I need to derive a concrete
subclass of datetime.tzinfo, and pass it to every datetime() object ?

Thanks,
Julien
