Ah, I think I have a partial answer... but not a complete answer.

I've looked inside the pgmodule.c source code, and it includes this 
snippet:


extern void
initpg(void)
{
    char *p;
    int i;

    Py_InitModule("pg", pg_methods);


which suggests that the pgmodule.so file creates a module called "pg". 
What I don't understand is how "import pg" gets turned into "run 
pgmodule.so"?
