hi, folks. I just follow the doc "The Joy of SQLAlchemy" at
http://docs.turbogears.org/1.0/SQLAlchemy. Everything is ok if I
"tg-admin sql create" by default sqlite uri. But after I change the uri
to postgresql and create it(no error occurs), every page of the site
return a traceback:

500 Internal error

The server encountered an unexpected condition which prevented it from
fulfilling the request.

Traceback (most recent call last):
  File

TypeError: can't compare offset-naive and offset-aware datetimes

Is the postgresql not compatible with SA and TG? thanks
