Actually, being more surgical and removing only wait_event.h, the
attached patch applies and compiles cleanly -- after yours this time,
rather than on master.  I think this is the most significant change
because of it including the generated file.  Given that pgstat.h is not
_so_ widely used, I think leaving the other includes there doesn't hurt
all that much anyway.
