Thanks for the review @kaknikhil .
1. We had an issue with the knn help messages during one of the releases
because they didn't show up on the `diff_udf.sql` output. IIRC, the problem was
that the same function was converted from a pure SQL function to a plpython
function. I don't have a quick solution to identify such cases.
2. This indentation should be OK.
3. We can check if the `new_vers` tag/branch exists and use `master` in its
place. Alternatively, we can change the comment to avoid using the new version.
It does not have any functional value.
