I personally would not be happier with that.  extern can be applied to
function prototypes, not just variables, and even to function
definitions.  When I see PGDLLIMPORT, I think, oh look, this is some
kind of magic pixie dust that Windows requires us to sprinkle on our
variables.  When I see pg_extern, I think, oh, this is the PostgreSQL
version of extern, and it's not, really.

But I can live with it if it makes other people sufficiently happier.
One way or another, I really do feel very strongly that we should push
forward with broader PGDLLIMPORT-ification.  My experience mirrors
Craig's: this is a very useful thing for extension developers.
