Well, there's nothing actually stopping you running a text string
fetched from a database rather than a file through the django template
system? OTOH, you might not actually want to expose full django
templating to blog post authors.
http://docs.djangoproject.com/en/dev/ref/templates/api/#rendering-a-context
./manage.py shell
from django.contrib.auth.models import User
from django.template import Template, Context
s = 'Hello <a href="{{ u.get_absolute_url }}">{{u.username}}</a>'
t = Template(s)
u = User.objects.get(username='blah')
c = Context(dict(u=u))
print t.render(c)
=> Hello <a href="/accounts/user/blah/">blah</a>
