Sure, look in the contrib directory in your source tree. There are lots
of examples there, for example look at contrib/fuzzystrmatch. Also see:
http://www.postgresql.org/idocs/index.php?xfunc-c.html

My main point was that if all of your I/O is going through the
functions, and the functions themselves are large and complex, you may
get a significant overall performance boost by using C functions instead.

Good luck!
