Drop Debian Stretch as it's EOL
It EOLs on June 30, 2022 per https://wiki.debian.org/LTS/Stretch. Keep bullseye from being the default on Postgres 10 or 11 (per #582).

# Users who know their applications do not keep open long-lived idle connections

# See also https://www.postgresql.org/docs/12/server-start.html for further

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.

documentation about "trust":
|
||||
https://www.postgresql.org/docs/current/auth-trust.html
|
||||
In Docker's default configuration, this is effectively any other
|
||||
container on the same system.
|
||||
|
||||
It is not recommended to use POSTGRES_HOST_AUTH_METHOD=trust. Replace
|
||||
it with "-e POSTGRES_PASSWORD=password" instead to set a password in
|
||||
"docker run".

# 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.

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.

It is not recommended to use POSTGRES_HOST_AUTH_METHOD=trust. Replace
