Re: Merge rows based on Levenshtein distance

There is nice extension in postgres: fuzzystrmatch
<http://www.postgresql.org/docs/9.3/static/fuzzystrmatch.html> I have used
to calculate the distance. From documetation:

SELECT levenshtein_less_equal('extensive', 'exhaustive',2);

You can use it then with your group by query.
