Barman 3.9.0

Version 3.9.0 - 3 October 2023

Features

• Allow barman switch-wal --force to be run against PG>=14 if the
  user has the pg_checkpoint role (thanks to toydarian for this patch).

• Log the current check at info level when a check timeout occurs.

• The minimum size of an upload chunk when using barman-cloud-backup
  with either S3 or Azure Blob Storage can now be specified using the
  --min-chunk-size option.

• backup_compression = none is supported when using pg_basebackup.

• For PostgreSQL 15 and later: the allowed backup_compression_level
  values for zstd and lz4 have been updated to match those allowed by
  pg_basebackup.

• For PostgreSQL versions earlier than 15: backup_compression_level = 0
  can now be used with backup_compression = gzip.

Bug fixes:

• Fix barman recover on platforms where Multiprocessing uses spawn by
  default when starting new processes.
