I'm quite interested, myself. How difficult is it for somebody that
doesn't program C to attach a function from the Contrib directory? If
it's not very difficult, then I'd recommend putting metaphone in
/contrib, and levenstein in the backend. My reasoning is that
levenstein is useful for all roman alphabets, but metaphone is not so
useful for non-english versions of postgres.
