-# We set the default STOPSIGNAL to SIGINT, which corresponds to what PostgreSQL
-# calls "Fast Shutdown mode" wherein new connections are disallowed and any
-# in-progress transactions are aborted, allowing PostgreSQL to stop cleanly and
-# flush tables to disk.
-#
-# See https://www.postgresql.org/docs/current/server-shutdown.html for more details
-# about available PostgreSQL server shutdown signals.
-#
-# See also https://www.postgresql.org/docs/current/server-start.html for further
-# justification of this as the default value, namely that the example (and
-# shipped) systemd service files use the "Fast Shutdown mode" for service
-# termination.

-# An additional setting that is recommended for all users regardless of this
-# value is the runtime "--stop-timeout" (or your orchestrator/runtime's
-# equivalent) for controlling how long to wait between sending the defined
-# STOPSIGNAL and sending SIGKILL.
-#
-# The default in most runtimes (such as Docker) is 10 seconds, and the
-# documentation at https://www.postgresql.org/docs/current/server-start.html notes
-# that even 90 seconds may not be long enough in many instances.
