It seems that on_shmem_exit() first argument is a function that
needs to be called back.  The function itself doesn't have a
prototype, but it's called with and int and Datum as argument
when it's used.

It seems that almost none of the functions it calls will actually
need any argument, I could only found 3 that actually use it.

Those most weird one was DummyProcKill, which itself doesn't take
any arguments, but it asked to be called with proctype as
argument.


Should I convert them all to take the 2 arguments instead, or
just leave it as is?

If you wish to clean up that area, feel free.  It could use it.
