Jinja2 highlight

I have installed jinja highlight in a small flask app. The highlighting works great when used directly in templates, but when I call it from the database and try to apply it on an entry, it does not render - it gives me the raw output from the db.

The code from the example:

{% highlight 'python' %}    
from fridge import Beer    
glass = Beer(lt=500)    
{% endhighlight %}

works in the template, but when I try to write and save an entry with the same content, the output is exactly the same, no formatting. I have tried {{ entry }}, {{entry|safe }} and the result is the same.

What am I doing wrong? While this is a particular jinja2 extension, I suppose the problem is more general.
