  (define-module (pg whatever)
    #:export (guile-pg symbols ...))
  
  (load-extension "libwhateverpg" "guile_pg_init")

Is roughly what you need. Assuming that there is an init function in
guile-pg that creates all of bindings for the library which, if I am
remembering how the autoloading magic works, it has to. This is
definitely something that anyone could do (just find the guile-pg init
function and export every scm_define_gsubr etc.).
