# 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, which is the best compromise available to avoid data
|
||
|
|
# corruption.
|
||
|
|
#
|
||
|
|
# Users who know their applications do not keep open long-lived idle connections
|
||
|
|
# may way to use a value of SIGTERM instead, which corresponds to "Smart
|
||
|
|
# Shutdown mode" in which any existing sessions are allowed to finish and the
|
||
|
|
# server stops when all sessions are terminated.
|
||
|
|
#
|
||
|
|
# See https://www.postgresql.org/docs/12/server-shutdown.html for more details
|
||
|
|
# about available PostgreSQL server shutdown signals.

||
|
|
#
|
||
|
|
# See also https://www.postgresql.org/docs/12/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.

STOPSIGNAL SIGINT
|
||
|
|
#
|
||
|
|
# 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 (which is likely to cause data corruption).
|
||
|
|
#
|
||
|
|
# The default in most runtimes (such as Docker) is 10 seconds, and the
|
||
|
|
# documentation at https://www.postgresql.org/docs/12/server-start.html notes
|
||
|
|
# that even 90 seconds may not be long enough in many instances.
