PPID should work fine, actually.  Keep in mind though that SIGINT'ing
the postmaster will already have sent a terminate signal to its children
(barring postmaster breakage), and that if you wait around for awhile
and then kill off remaining children, you may well accomplish nothing
except to kill off the checkpoint process :-(
