Log message:
Update databases/py-barman to 1.4.1.

Version 1.4.1 - 05 May 2015
  * Fix for WAL archival stop working if first backup is EMPTY
    (Closes: #64)
  * Fix exception during error handling in Barman recovery (Closes:
    #65)
  * After a backup, limit cron activity to WAL archiving only
    (Closes: #62)
  * Improved robustness and error reporting of the backup delete
    command (Closes: #63)
  * Fix computation of WAL production ratio as reported in the
    show-backup command
  * Improved management of xlogb file, which is now correctly fsynced
    when updated. Also, the rebuild-xlogdb command now operates on a
    temporary new file, which overwrites the main one when finished.
  * Add unit tests for dateutil module compatibility
  * Modified Barman version following PEP 440 rules and added support
    of tests in Python 3.4

Log message:
Removing python26. EOL'd quite some ago and discussed a couple times on

Log message:
Update py-barman to 1.4.0.

Version 1.4.0 - 26 Jan 2015

  * Incremental base backup implementation through the reuse_backup
    global/server option. Possible values are off (disabled,
    default), copy (preventing unmodified files from being
    transferred) and link (allowing for deduplication through hard
    links).
  * Store and show deduplication effects when using reuse_backup=
    link.
  * Added transparent support of pg_stat_archiver (PostgreSQL 9.4) in
    check, show-server and status commands.
  * Improved administration by invoking WAL maintenance at the end of
    a successful backup.
  * Changed the way unused WAL files are trashed, by differentiating
    between concurrent and exclusive backup cases.
  * Improved performance of WAL statistics calculation.
  * Treat a missing pg_ident.conf as a WARNING rather than an error.
  * Refactored output layer by removing remaining yield calls.
  * Check that rsync is in the system path.
  * Include history files in WAL management.
  * Improved robustness through more unit tests.
  * Fixed bug #55: Ignore fsync EINVAL errors on directories.
  * Fixed bug #58: retention policies delete.
