Subject: pgsql: Kill dead-end children when there's nothing else left

Message-ID: <E1tBaaw-001mW8-Oq@gemulon.postgresql.org> (raw)
Kill dead-end children when there's nothing else left
Previously, the postmaster would never try to kill dead-end child
processes, even if there were no other processes left. A dead-end
backend will eventually exit, when authentication_timeout expires, but
if a dead-end backend is the only thing that's preventing the server
from shutting down, it seems better to kill it immediately. It's
particularly important, if there was a bug in the early startup code
that prevented a dead-end child from timing out and exiting normally.
Includes a test for that case where a dead-end backend previously
prevented the server from shutting down.
