-repmgrd's failover algorithm
-============================
-
-When implementing automatic failover, there are two factors which are critical in
-ensuring the desired result is achieved:
-
-  - has the master node genuinely failed?
-  - which is the best node to promote to the new master?
-
-This document outlines repmgrd's decision-making process during automatic failover
-for standbys directly connected to the master node.
-
-
-Master node failure detection
------------------------------
-
-If a `repmgrd` instance running on a PostgreSQL standby node is unable to connect to
-the master node, this doesn't neccesarily mean that the master is down and a
-failover is required. Factors such as network connectivity issues could mean that
-even though the standby node is isolated, the replication cluster as a whole
-is functioning correctly, and promoting the standby without further verification
-could result in a "split-brain" situation.
-
-In the event that `repmgrd` is unable to connect to the master node, it will attempt
-to reconnect to the master server several times (as defined by the `reconnect_attempts`
-parameter in `repmgr.conf`), with reconnection attempts  occuring at the interval
-specified by `reconnect_interval`. This happens to verify that the master is definitively
-not accessible (e.g. that connection was not lost due to a brief network glitch).
-
-Appropriate values for these settings will depend very much on the replication
-cluster environment. There will necessarily be a trade-off between the time it
-takes to assume the master is not reachable, and the reliability of that conclusion.
-A standby in a different physical location to the master will probably need a longer
-check interval to rule out possible network issues, whereas one located in the same
-rack with a direct connection between servers could perform the check very quickly.
-
-Note that it's possible the master comes back online after this point is reached,
-but before a new master has been selected; in this case it will be noticed
-during the selection of a new master and no actual failover will take place.
-
-Promotion candidate selection
------------------------------
-
-Once `repmgrd` has decided the master is definitively unreachable, following checks
-will be carried out:
-
-* attempts to connect to all other nodes in the cluster (including the witness
-  node, if defined) to establish the state of the cluster, including their
-  current LSN
-
-* If less than half of the nodes are visible (from the viewpoint
-  of this node), `repmgrd` will not take any further action. This is to ensure that
-  e.g. if a replication cluster is spread over multiple data centres, a split-brain
-  situation does not occur if there is a network failure between datacentres. Note
-  that if nodes are split evenly between data centres, a witness server can be
-  used to establish the "majority" data centre.
-
-* `repmgrd` polls all visible servers and waits for each node to return a valid LSN;
-  it updates the LSN previously  stored for this node if it has increased since
-  the initial check
-
-* once all LSNs have been retrieved, `repmgrd` will check for the highest LSN; if
-  its own node has the highest LSN, it will attempt to promote itself (using the
-  command defined in `promote_command` in `repmgr.conf`. Note that if using
-  `repmgr standby promote` as the promotion command, and the original master becomes available
-  before the promotion takes effect, `repmgr` will return an error and no promotion
-  will take place, and `repmgrd` will resume monitoring as usual.
-
-* if the node is not the promotion candidate, `repmgrd` will execute the
-  `follow_command` defined in `repmgr.conf`. If using `repmgr standby follow` here,
-  `repmgr` will attempt to detect the new master node and attach to that.

-Fencing a failed master node with repmgrd and pgbouncer
-=======================================================
-
-With automatic failover, it's essential to ensure that a failed master
-remains inaccessible to your application, even if it comes back online
-again, to avoid a split-brain situation.
-
-By using `pgbouncer` together with `repmgrd`, it's possible to combine
-automatic failover with a process to isolate the failed master from
-your application and ensure that all connections which should go to
-the master are directed there smoothly without having to reconfigure
-your application. (Note that as a connection pooler, `pgbouncer` can
-benefit your application in other ways, but those are beyond the scope
-of this document).
-
-* * *
-
-> *WARNING*: automatic failover is tricky to get right. This document
-> demonstrates one possible implementation method, however you should
-> carefully configure and test any setup to suit the needs of your own
-> replication cluster/application.
-
-* * *
-
-In a failover situation, `repmgrd` promotes a standby to master by executing
-the command defined in `promote_command`. Normally this would be something like:
-
-    repmgr standby promote -f /etc/repmgr.conf
-
-By wrapping this in a custom script which adjusts the `pgbouncer` configuration
-on all nodes, it's possible to fence the failed master and redirect write
-connections to the new master.
-
-The script consists of three sections:
-
-* commands to pause `pgbouncer` on all nodes
-* the promotion command itself
-* commands to reconfigure and restart `pgbouncer` on all nodes
-
-Note that it requires password-less SSH access between all nodes to be able to
-update the `pgbouncer` configuration files.
-
-For the purposes of this demonstration, we'll assume there are 3 nodes (master
-and two standbys), with `pgbouncer` listening on port 6432 handling connections
-to a database called `appdb`.  The `postgres` system user must have write
-access to the `pgbouncer` configuration files on all nodes. We'll assume
-there's a main `pgbouncer` configuration file, `/etc/pgbouncer.ini`, which uses
-the `%include` directive (available from PgBouncer 1.6) to include a separate
-configuration file, `/etc/pgbouncer.database.ini`, which will be modified by
-`repmgr`.
-
-`/etc/pgbouncer.ini` should look something like this:
-
-    [pgbouncer]
-
-    logfile = /var/log/pgbouncer/pgbouncer.log
-    pidfile = /var/run/pgbouncer/pgbouncer.pid
-
-    listen_addr = *
-    listen_port = 6532
-    unix_socket_dir = /tmp
-
-    auth_type = trust
-    auth_file = /etc/pgbouncer.auth
-
-    admin_users = postgres
-    stats_users = postgres
-
-    pool_mode = transaction
-
-    max_client_conn = 100
-    default_pool_size = 20
-    min_pool_size = 5
-    reserve_pool_size = 5
-    reserve_pool_timeout = 3
-
-    log_connections = 1
-    log_disconnections = 1
-    log_pooler_errors = 1
-
-    %include /etc/pgbouncer.database.ini
-
-The actual script is as follows; adjust the configurable items as appropriate:
-
-`/var/lib/postgres/repmgr/promote.sh`
-
-
-    #!/usr/bin/env bash
-    set -u
-    set -e

-    do
-        psql -t -c "pause" -h $HOST -p $PGBOUNCER_PORT -U postgres pgbouncer
-    done
-
-    # 2. Promote this node from standby to master
-
-    repmgr standby promote -f /etc/repmgr.conf
-
-    # 3. Reconfigure pgbouncer instances
-
-    PGBOUNCER_DATABASE_INI_NEW="/tmp/pgbouncer.database.ini"
-
-    for HOST in $PGBOUNCER_HOSTS
-    do
-        # Recreate the pgbouncer config file
-        echo -e "[databases]\n" > $PGBOUNCER_DATABASE_INI_NEW

-          -c "SELECT '${PGBOUNCER_DATABASE}-rw= ' || conninfo || ' application_name=pgbouncer_${HOST}' \

-

-
-        psql -tc "reload" -h $HOST -p $PGBOUNCER_PORT -U postgres pgbouncer
-        psql -tc "resume" -h $HOST -p $PGBOUNCER_PORT -U postgres pgbouncer
-
-    done
-
-    # Clean up generated file
-    rm $PGBOUNCER_DATABASE_INI_NEW
-
-    echo "Reconfiguration of pgbouncer complete"
-
-Script and template file should be installed on each node where
-`repmgrd` is running.
-
-Finally, set `promote_command` in `repmgr.conf` on each node to
-point to the custom promote script:
-
-    promote_command=/var/lib/postgres/repmgr/promote.sh
-
-and reload/restart any running `repmgrd` instances for the changes to take
-effect.
