Known issues in repmgr
======================

* When running repmgr against a remote machine, operations that start
  the database server using the ``pg_ctl`` command may accidentally
  terminate after their associated ssh session ends.

* PGPASSFILE may not be passed to pg_basebackup


Planned feature improvements
============================

* Use 'primary' instead of 'master' in documentation and log output
  for consistency with PostgreSQL documentation. See also commit
  870b0a53b627eeb9aca1fc14cbafe25b5beafe12.

* A better check which standby did receive most of the data

* Make the fact that a standby may be delayed a factor in the voting
  algorithm

* include support for delayed standbys

* Create the repmgr user/database on "master register".

* Use pg_basebackup for the data directory, and ALSO rsync for the
  configuration files.

* If no configuration file supplied, search in sensible default locations
  (currently: current directory and `pg_config --sysconfdir`); if
  possible this should include the location provided by the package,
  if installed.

* repmgrd: if connection to the upstream node fails on startup, optionally
  retry for a certain period before giving up; this will cover cases when
  e.g. primary and standby are both starting up, and the standby comes up
  before the primary. See github issue #80.

* make old master node ID available for event notification commands
  (See github issue #80).

* Have pg_basebackup use replication slots, if and when support for
  this is added; see:
    http://www.postgresql.org/message-id/555DD2B2.7020000@gmx.net

* use "primary/standby" terminology in place of "master/slave" for consistency
  with main PostrgreSQL usage

* repmgr standby clone: possibility to use barman instead of performing a new base backup

* possibility to transform a failed master into a new standby with pg_rewind

* "repmgr standby switchover" to promote a standby in a controlled manner
   and convert the existing primary into a standby

* make repmgrd more robust

Usability improvements
======================

* repmgrd: on failover, explicitly log which node is now being followed

* repmgr: add explicit --log-level flag, repurpose --verbose flag to
  show extra detailed/repetitive output only (see item below too)

* debug output: show some repetitive output only if --verbose flag set to prevent
  excessive log growth
