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

# justification of this as the default value, namely that the example (and

# 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.

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

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

It is not recommended to use POSTGRES_HOST_AUTH_METHOD=trust. Replace

Error: Database is uninitialized and superuser password is not specified.

You must specify POSTGRES_PASSWORD to a non-empty value for the

|

|

You may also use "POSTGRES_HOST_AUTH_METHOD=trust" to allow all

connections without a password. This is *not* recommended.

********************************************************************************
|

WARNING: POSTGRES_HOST_AUTH_METHOD has been set to "trust". This will allow
|
||||
anyone with access to the Postgres port to access your database without
|
||||
a password, even if POSTGRES_PASSWORD is set. See PostgreSQL
|
||||
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".
