It's intentional. If you don't want that, use SIGQUIT. That's how they
are different.
Of course, when using SIGQUIT, you will have to spend the time you saved
on the checkpoint for the recovery at startup. So you have to put in
the time either way.
It is not unheard of that a shutdown can take minutes. That's why the
-t option was added to pg_ctl some time ago.
