> Hello,
> I got a few questions as follows:
> 1.  Which one is the best way for Fuzzy Address Matching?
> 2.  FME FuzzyStringComparer uses  Python difflib module.  Which one in
> Postgres is equivalent or similar to it?
> 3.  Often, addresses collected by different people may well be correct.
> But, there may be typing errors, or addresses are composed not in a

> the following:
> S. Great Aveue, City A, Earth Planet
> Great Avene South, A City, Earth Planet
> Great Avenue S, A City, Planet Earth
> Surely, there would be solutions to deal with this problem.
> Can anyone enlighten me?
