No. Or yeah, we could, but that patch would add no security worth
mentioning. For example, someone could launch a query that runs for
many minutes, and would have plenty of time to conflict with a
subsequently-started postmaster.
Even without that issue, there's no consensus that forcibly making
orphan backends exit would be a good thing. (Some people would
like to have such an option, but the key word in that sentence is
"option".)
