Good afternoon,

Under PostgreSQL 8.0.15, what is the good function to do the Fuzzy match 
between two strings?

For example,
(1) 'abcddd' vs. 'abc'    probably returns 3

(2) 'abcddd' vs. 'ab'    probably returns 4

I am looking for functions that could compare how two strings are 
similar to each other.

thanks a lot!
