Webware for Python

Sauda=E7=F5es,

    I am in process of choosing the tecnology for the new website.
    Webware seems to be amazing for developing a web application.
    But I have some doubts about building the infrastructure:
    - Middlekit does not support Postgresql. There are any other way or=20
workaround?
    - How Middlekit controls database transactions ?
    - I couldn't understand if Middlekit does some object caching or if i=
s a=20
object wrapper over SQL language.

    Thanks,
