Yes it is, because sigkill can't be trapped --- it causes instant
process death with no chance to clean up. Not that we have backends
do a lot of cleanup after sigquit either, but at least the option
exists. The real difference is in the postmaster: kill -9 on the
postmaster is a seriously bad idea, because it gets no chance to shut
down its children.
