Version 3.0.0 - 23 June 2022

Features

• BREAKING CHANGE: PostgreSQL versions 9.6 and earlier are no longer
  supported. If you are using one of these versions you will need to
  use an earlier version of Barman.

• BREAKING CHANGE: The default backup mode for Rsync backups is now
  concurrent rather than exclusive. Exclusive backups have been
  deprecated since PostgreSQL 9.6 and have been removed in PostgreSQL
  15. If you are running Barman against PostgreSQL versions earlier
  than 15 and want to use exclusive backups you will now need to set
  exclusive_backup in backup_options.

• BREAKING CHANGE: The backup metadata stored in the backup.info file
  for each backup has an extra field. This means that earlier versions
  of Barman will not work in the presence of any backups taken with
  3.0.0. Additionally, users of pg-backup-api will need to upgrade it
  to version 0.2.0 so that pg-backup-api can work with the updated
  metadata.

• Backups taken with backup_method = postgres can now be compressed
  by pg_basebackup by setting the backup_compression config option.
  Additional options are provided to control the compression level,
  the backup format and whether the pg_basebackup client or the
  PostgreSQL server applies the compression. NOTE: Recovery of these
  backups requires Barman to stage the compressed files on the recovery
  server in a location specified by the recovery_staging_path option.

• Add support for PostgreSQL 15. Exclusive backups are not supported
  by PostgreSQL 15 therefore Barman configurations for PostgreSQL 15
  servers are not allowed to specify exclusive_backup in
  backup_options.

• Various documentation improvements.

• Use custom_compression_magic, if set, when identifying compressed
  WAL files. This allows Barman to correctly identify uncompressed
  WALs (such as *.partial files in the streaming directory) and
  return them instead of attempting to decompress them.

Bug fixes

• Fix an ordering bug which caused Barman to log the message
  "Backup failed issuing start backup command." while handling a
  failure in the stop backup command.

• Fix a bug which prevented recovery using --target-tli when
  timelines greater than 9 were present, due to hexadecimal values
  from WAL segment names being parsed as base 10 integers.

• Fix an import error which occurs when using barman cloud with
  certain python2 installations due to issues with the enum34
  dependency.

• Fix a bug where Barman would not read more than three bytes from
  a compressed WAL when attempting to identify the magic bytes. This
  means that any custom compressed WALs using magic longer than three
  bytes are now decompressed correctly.

• Fix a bug which caused the --immediate-checkpoint flag to be
  ignored during backups with backup_method = rsync.
