The "C-Language Functions" documentation explains:

http://www.postgresql.org/docs/8.1/interactive/xfunc-c.html

"After it is used for the first time, a dynamically loaded object
file is retained in memory.  Future calls in the same session to
the function(s) in that file will only incur the small overhead of
a symbol table lookup.  If you need to force a reload of an object
file, for example after recompiling it, use the LOAD command or
begin a fresh session."
