PhantomJS looks interesting. Can it 1) Read/write a Postgres database, and 2) Fill in form fields and submit forms, with the javascript associated with the various events firing automatically. I looked at the PhantomJS website but didn't find any examples of these uses; it would be helpful if you could point me at examples.
If PhantomJS cannot access Postgres, is there a typical usage pattern for PhantomJS code that uses it as a helper to retrieve pages and return them to the caller for further processing?
