# repmgr sample configuration file
###################################################
# Some configuration items will be set with a default value; this
# is noted for each item. Where no default value is shown, the
# parameter will be treated as empty or false.
#
# repmgr parses its configuration file in the same way as PostgreSQL itself
# does. In particular, strings must be enclosed in single quotes (although
# simple identifiers may be provided as-is).
#
# For details on the configuration file format see the documentation at:
#
# https://repmgr.org/docs/current/configuration-file.html#CONFIGURATION-FILE-FORMAT
#
# =============================================================================
# Required configuration items
# =============================================================================
#
# repmgr and repmgrd require the following items to be explicitly configured.
#node_id= # A unique integer greater than zero
#node_name='' # An arbitrary (but unique) string; we recommend
# using the server's hostname or another identifier
# unambiguously associated with the server to avoid
# confusion. Avoid choosing names which reflect the
# node's current role, e.g. 'primary' or 'standby1',
# as roles can change and it will be confusing if
# the current primary is called 'standby1'.
# The string's maximum length is 63 characters and it should
# contain only printable ASCII characters.
#conninfo='' # Database connection information as a conninfo string.
# All servers in the cluster must be able to connect to
# the local node using this string.
#
# For details on conninfo strings, see:
# https://www.postgresql.org/docs/current/libpq-connect.html#LIBPQ-CONNSTRING
#
# If repmgrd is in use, consider explicitly setting
# "connect_timeout" in the conninfo string to determine
# the length of time which elapses before a network
# connection attempt is abandoned; for details see:
# https://www.postgresql.org/docs/current/libpq-connect.html#LIBPQ-CONNECT-CONNECT-TIMEOUT
#data_directory='' # The node's data directory. This is needed by repmgr
# when performing operations when the PostgreSQL instance
# is not running and there's no other way of determining
# the data directory.
# =============================================================================
# Optional configuration items
# =============================================================================
#------------------------------------------------------------------------------
# Server settings
#------------------------------------------------------------------------------
#config_directory='' # If configuration files are located outside the data
# directory, specify the directory where the main
# postgresql.conf file is located.
#------------------------------------------------------------------------------
# Replication settings
#------------------------------------------------------------------------------
#replication_user='repmgr' # User to make replication connections with, if not set
# defaults to the user defined in "conninfo".
#replication_type='physical' # Must "physical" (the default).
#location='default' # An arbitrary string defining the location of the node; this
# is used during failover to check visibility of the
# current primary node. For further details see:
# https://repmgr.org/docs/current/repmgrd-network-split.html
#use_replication_slots=no # whether to use physical replication slots
# NOTE: when using replication slots,
# 'max_replication_slots' should be configured for
# at least the number of standbys which will connect
# to the primary.
#------------------------------------------------------------------------------
# Witness server settings
#------------------------------------------------------------------------------
#witness_sync_interval=15 # interval (in seconds) to synchronise node records
# to the witness server
#------------------------------------------------------------------------------
# Logging settings
#------------------------------------------------------------------------------
#
# Note that logging facility settings will only apply to `repmgrd` by default;
# `repmgr` will always write to STDERR unless the switch `--log-to-file` is
# supplied, in which case it will log to the same destination as `repmgrd`.
# This is mainly intended for those cases when `repmgr` is executed directly
# by `repmgrd`.
#log_level='INFO' # Log level: possible values are DEBUG, INFO, NOTICE,
# WARNING, ERROR, ALERT, CRIT or EMERG
#log_facility='STDERR' # Logging facility: possible values are STDERR, or for
# syslog integration, one of LOCAL0, LOCAL1, ..., LOCAL7, USER
#log_file='' # STDERR can be redirected to an arbitrary file
#log_status_interval=300 # interval (in seconds) for repmgrd to log a status message
#------------------------------------------------------------------------------
# Event notification settings
#------------------------------------------------------------------------------
# event notifications can be passed to an arbitrary external program
# together with the following parameters:
#
# %n - node ID
# %e - event type
# %s - success (1 or 0)
# %t - timestamp
# %d - details
#
# the values provided for "%t" and "%d" will probably contain spaces,
# so should be quoted in the provided command configuration, e.g.:
#
# event_notification_command='/path/to/some/script %n %e %s "%t" "%d"'
#
# By default, all notifications will be passed; the notification types
# can be filtered to explicitly named ones, e.g.:
#
# event_notifications=primary_register,standby_register
#event_notification_command='' # An external program or script which
# can be executed by the user under which
# repmgr/repmgrd are run.
#event_notifications='' # A commas-separated list of notification
# types
#------------------------------------------------------------------------------
# Environment/command settings
#------------------------------------------------------------------------------
#pg_bindir='' # Path to PostgreSQL binary directory (location
# of pg_ctl, pg_basebackup etc.). Only needed
# if these files are not in the system $PATH.
#
# Debian/Ubuntu users: you will probably need to
# set this to the directory where `pg_ctl` is located,
# e.g. /usr/lib/postgresql/9.6/bin/
#
# *NOTE* "pg_bindir" is only used when repmgr directly
# executes PostgreSQL binaries; any user-defined scripts
# *must* be specified with the full path
#repmgr_bindir='' # Path to repmgr binary directory (location of the repmgr
# binary. Only needed if the repmgr executable is not in
# the system $PATH or the path defined in "pg_bindir".
#use_primary_conninfo_password=false # explicitly set "password" in "primary_conninfo"
# using the value contained in the environment variable
# PGPASSWORD
#passfile='' # path to .pgpass file to include in "primary_conninfo"
#------------------------------------------------------------------------------
# external command options
#------------------------------------------------------------------------------
#
# Options which can be passed to external commands invoked by repmgr/repmgrd.
#
# Examples:
#
# pg_ctl_options='-s'
# pg_basebackup_options='--label=repmgr_backup'
# rsync_options=--archive --checksum --compress --progress --rsh="ssh -o \"StrictHostKeyChecking no\""
# ssh_options=-o "StrictHostKeyChecking no"
#pg_ctl_options='' # Options to append to "pg_ctl"
#pg_basebackup_options='' # Options to append to "pg_basebackup"
# (Note: when cloning from Barman, repmgr will honour any
# --waldir/--xlogdir setting present in "pg_basebackup_options"
#rsync_options='' # Options to append to "rsync"
ssh_options='-q -o ConnectTimeout=10' # Options to append to "ssh"
#------------------------------------------------------------------------------
# "standby clone" settings
#------------------------------------------------------------------------------
#
# These settings apply when cloning a standby ("repmgr standby clone").
#
# Examples:
#
# tablespace_mapping='/path/to/original/tablespace=/path/to/new/tablespace'
# restore_command = 'cp /path/to/archived/wals/%f %p'
#tablespace_mapping='' # Tablespaces can be remapped from one
# file system location to another. This
# parameter can be provided multiple times.
#restore_command='' # This will be included in the recovery configuration
# generated by repmgr.
#archive_cleanup_command='' # This will be included in the recovery configuration
# generated by repmgr. Note we recommend using Barman for
# managing WAL archives (see: https://www.pgbarman.org )
#recovery_min_apply_delay= # If provided, "recovery_min_apply_delay" will be set to
# this value (PostgreSQL 9.4 and later). Value can be
# an integer representing milliseconds, or a string
# representing a period of time (e.g. '5 min').

#------------------------------------------------------------------------------
# These settings apply when instructing a standby to promote itself to the
# new primary ("repmgr standby promote").

#------------------------------------------------------------------------------
# Failover and monitoring settings (repmgrd)
#------------------------------------------------------------------------------
#
# These settings are only applied when repmgrd is running. Values shown
# are defaults.
#failover='manual' # one of 'automatic', 'manual'.
# determines what action to take in the event of upstream failure
#
# 'automatic': repmgrd will automatically attempt to promote the
# node or follow the new upstream node
# 'manual': repmgrd will take no action and the node will require
# manual attention to reattach it to replication
#priority=100 # indicates a preferred priority for promoting nodes;
# a value of zero prevents the node being promoted to primary
# (default: 100)

#monitoring_history=no # Whether to write monitoring data to the "monitoring_history" table
#monitor_interval_secs=2 # Interval (in seconds) at which to write monitoring data
#degraded_monitoring_timeout=-1 # Interval (in seconds) after which repmgrd will terminate if the
# server(s) being monitored are no longer available. -1 (default)
# disables the timeout completely.
#async_query_timeout=60 # Interval (in seconds) which repmgrd will wait before
# cancelling an asynchronous query.
#repmgrd_pid_file= # Path of PID file to use for repmgrd; if not set, a PID file will
# be generated in a temporary directory specified by the environment
# variable $TMPDIR, or if not set, in "/tmp". This value can be overridden
# by the command line option "-p/--pid-file"; the command line option

# repmgr was installed from packages.
#repmgrd_exit_on_inactive_node=false # If "true", and the node record is marked as "inactive", abort repmgrd startup
#standby_disconnect_on_failover=false # If "true", in a failover situation wait for all standbys to

#always_promote=false # Always promote a node, even if repmgr metadata is outdated
#failover_validation_command='' # Script to execute for an external mechanism to validate the failover
# decision made by repmgrd. One or both of the following parameter placeholders
# should be provided, which will be replaced by repmgrd with the appropriate

#------------------------------------------------------------------------------
# service control commands
#------------------------------------------------------------------------------
#
# repmgr provides options to override the default pg_ctl commands
# used to stop, start, restart, reload and promote the PostgreSQL cluster
#
# These options are useful when PostgreSQL has been installed from a package
# which provides OS-level service commands. In environments using an init system
# such as systemd, which keeps track of the state of various services, it is
# essential that the service commands are correctly configured and pg_ctl is
# not executed directly.
#
# NOTE: These commands must be runnable on remote nodes as well for switchover
# to function correctly.
#
# If you use sudo, the user repmgr runs as (usually 'postgres') must have
# passwordless sudo access to execute the command.
#
# For example, to use systemd, you can set
#
# service_start_command = 'sudo systemctl start postgresql-9.6'
# (...)
#
# and then use the following sudoers configuration:
#
# # this is required when running sudo over ssh without -t:
# Defaults:postgres !requiretty
# postgres ALL = NOPASSWD: /usr/bin/systemctl stop postgresql-9.6, \
# /usr/bin/systemctl start postgresql-9.6, \
# /usr/bin/systemctl restart postgresql-9.6
#
# Debian/Ubuntu users: use "sudo pg_ctlcluster" to execute service control commands.
