As far as I know, you need to compile the function as a dynamic object:
from:
http://postgresql.crimelabs.net/users-lounge/docs/7.0/user/sql-createfunction.htm
obj_file , link_symbol
This form of the AS clause is used for dynamically-linked, C
language functions when the function name in the C language source code
is not the
same as the name of the SQL function. The string obj_file is the
name of the file containing the dynamically loadable object, and
link_symbol, is
the object's link symbol which is the same as the name of the
function in the C language source code.
Where did you find this example?
