Comment (by Mjumbe Poe):

 I've started adding some tests at
 https://github.com/mjumbewu/django/tree/postgis22_deprecated. I tried
 handling the pre/post PostGIS 2.2 condition in there as well. It's not the
 most elegant solution, and it's not easy to test, since the PostGIS
 version is cached after it's first calculated (so I can't just
 {{{override_settings}}}). I had to test it by just running the tests twice
 against different postgis versions (which is why there are test in there
 commented out). Can anyone else think of better tests for this?
