I was thinking along the same lines myself. I'd want to do it on a
per-function basis, though, rather than assuming that all functions in
a module must use the same interface.
I'd be inclined to define a macro that creates the signal object,
so that you'd write something like
PG_FUNCTION_API_V2(foo);
Datum
foo(PG_FUNCTION_ARGS)
{
...
}
to create a dynamically loadable new-style function.
Comments?
