# -------------------------------
# PostgreSQL recovery config file
# -------------------------------
#
# Edit this file to provide the parameters that PostgreSQL needs to
# perform an archive recovery of a database, or to act as a replication
# standby.
#
# If "recovery.conf" is present in the PostgreSQL data directory, it is
# read on postmaster startup.  After successful recovery, it is renamed
# to "recovery.done" to ensure that we do not accidentally re-enter
# archive recovery or standby mode.
#
# This file consists of lines of the form:
#
#   name = value
#
# Comments are introduced with '#'.
#
# The complete list of option names and allowed values can be found
# in the PostgreSQL documentation.
#
#---------------------------------------------------------------------------
# ARCHIVE RECOVERY PARAMETERS
#---------------------------------------------------------------------------
#
# restore_command
#
# specifies the shell command that is executed to copy log files
# back from archival storage.  The command string may contain %f,
# which is replaced by the name of the desired log file, and %p,
# which is replaced by the absolute path to copy the log file to.
#
# This parameter is *required* for an archive recovery, but optional
# for streaming replication.
#
# It is important that the command return nonzero exit status on failure.
# The command *will* be asked for log files that are not present in the
# archive; it must return nonzero when so asked.
#
# NOTE that the basename of %p will be different from %f; do not
# expect them to be interchangeable.
#
#restore_command = ''		# e.g. 'cp /mnt/server/archivedir/%f %p'
#
#
# archive_cleanup_command
#
# specifies an optional shell command to execute at every restartpoint.
# This can be useful for cleaning up the archive of a standby server.
#
#archive_cleanup_command = ''
#
# recovery_end_command
#
# specifies an optional shell command to execute at completion of recovery.
# This can be useful for cleaning up after the restore_command.
#
#recovery_end_command = ''
#
#---------------------------------------------------------------------------
# RECOVERY TARGET PARAMETERS
#---------------------------------------------------------------------------
#
# By default, recovery will rollforward to the end of the WAL log.
# If you want to stop rollforward at a specific point, you
# must set a recovery target.
#
# You may set a recovery target either by transactionId, by name,
# or by timestamp. Recovery may either include or exclude the
# transaction(s) with the recovery target value (ie, stop either
# just after or just before the given target, respectively).
#
#
#recovery_target_name = ''	# e.g. 'daily backup 2011-01-26'
#
#recovery_target_time = ''	# e.g. '2004-07-14 22:39:00 EST'
#
#recovery_target_xid = ''
#
#recovery_target_inclusive = true
#
#
# Alternatively, you can request stopping as soon as a consistent state
# is reached, by uncommenting this option.
#
#recovery_target = 'immediate'
#
#
# If you want to recover into a timeline other than the "main line" shown in
# pg_control, specify the timeline number here, or write 'latest' to get
# the latest branch for which there's a history file.
#
#recovery_target_timeline = 'latest'
#
#
# If recovery_target_action = 'pause', recovery will pause when the
# recovery target is reached. The pause state will continue until
# pg_xlog_replay_resume() is called. This setting has no effect if
# no recovery target is set. If hot_standby is not enabled then the
# server will shutdown instead, though you may request this in
# any case by specifying 'shutdown'.
#
#recovery_target_action = 'pause'
#
#---------------------------------------------------------------------------
# STANDBY SERVER PARAMETERS
#---------------------------------------------------------------------------
#
# standby_mode
#
# When standby_mode is enabled, the PostgreSQL server will work as a
# standby. It will continuously wait for the additional XLOG records, using
# restore_command and/or primary_conninfo.
#
#standby_mode = off
#
# primary_conninfo
#
# If set, the PostgreSQL server will try to connect to the primary using this
# connection string and receive XLOG records continuously.
#
#primary_conninfo = ''		# e.g. 'host=localhost port=5432'
#
# If set, the PostgreSQL server will use the specified replication slot when
# connecting to the primary via streaming replication to control resource
# removal on the upstream node. This setting has no effect if primary_conninfo
# is not set.
#
#primary_slot_name = ''
#
# By default, a standby server keeps restoring XLOG records from the
# primary indefinitely. If you want to stop the standby mode, finish recovery
# and open the system in read/write mode, specify a path to a trigger file.
# The server will poll the trigger file path periodically and start as a
# primary server when it's found.
#
#trigger_file = ''
#
# By default, a standby server restores XLOG records from the primary as
# soon as possible. If you want to explicitly delay the replay of committed
# transactions from the master, specify a minimum apply delay. For example,
# if you set this parameter to 5min, the standby will replay each transaction
# commit only when the system time on the standby is at least five minutes
# past the commit time reported by the master.
#
#recovery_min_apply_delay = 0
#
#---------------------------------------------------------------------------
# HOT STANDBY PARAMETERS
#---------------------------------------------------------------------------
#
# Hot Standby related parameters are listed in postgresql.conf
#
#---------------------------------------------------------------------------
