发行说明：

• Added "last_backup_max_age", a new global/server option that    allows administrators to set the max age of the last backup in a    catalogue, making it easier to detect any issues with periodical    backup execution

• Improved robustness of "barman backup" by introducing two    global/server options: "basebackup_retry_times" and    "basebackup_retry_sleep". These options allow an administrator to    specify, respectively, the number of attempts for a copy operation    after a failure, and the number of seconds of wait before retrying

• Improved the recovery process via rsync on an existing directory    (incremental recovery), by splitting the previous rsync call into    several ones - invoking checksum control only when necessary

• Added support for PostgreSQL 8.3

• Minor changes:

• Support for comma separated list values configuration options

• Improved backup durability by calling fsync() on backup and WAL    files during "barman backup" and "barman cron"

• Improved Nagios output for "barman check --nagios"

• Display compression ratio for WALs in "barman show-backup"

• Correctly handled keyboard interruption (CTRL-C) while    performing barman backup

• Improved error messages of failures regarding the stop of a    backup

• Wider coverage of unit tests

• Bug fixes:

• Copies "recovery.conf" on the remote server during "barman    recover" (#43)

• Correctly detect pre/post archive hook scripts (#41)
