There was once a discussion about allowing people to add declarations
to the C code indicating the types and returns type to avoid stupid
errors (you could just say CREATE FUNCTION foo FROM module.so and it
would get the types/volitility/etc from the module).

It even went so far that you could build the install/deinstall scripts
into the module itself, so all postgres had to do was dlopen() the
module it could access the install script. It fails due to the fact
that modules that don't require compilation are left out in the cold...

Have a nice day,
