Bug Fixes:
* Fixed an issue where read-only operations that used local worker processes (i.e. restore) were creating write locks that could interfere with parallel archive-push. (Reported by Jens Wilke.)
Features:
* Added the stanza-upgrade command to provide a mechanism for upgrading a stanza after upgrading to a new major version of PostgreSQL. (Contributed by Cynthia Shang.)
* Added validation of pgbackrest.conf to display warnings if options are not valid or are not in the correct section. (Contributed by Cynthia Shang.)
Refactoring:
* Simplify locking scheme. Now, only the master process will hold write locks (for archive-push and backup commands) and not all local and remote worker processes as before.
* Refactor Ini.pm to facilitate testing.
* Do not set timestamps of files in the backup directories to match timestamps in the cluster directory. This was originally done to enable backup resume, but that process is now implemented with checksums.
* Improved error message when the restore command detects the presence of postmaster.pid. (Suggested by Yogesh Sharma.)
* Renumber return codes between 25 and 125 to avoid PostgreSQL interpreting some as fatal signal exceptions. (Suggested by Yogesh Sharma.)
* The backup and restore commands no longer copy via temp files. In both cases the files are checksummed on resume so there's no danger of partial copies.
* Allow functions to accept optional parameters as a hash.
* Refactor File->list() and fileList() to accept optional parameters.
* Refactor backupLabel() and add unit tests.
* Silence some perl critic warnings. (Contributed by Cynthia Shang.)
Making this dynamic in commit 5d2e792 broke doc builds from cache. The long-term solution is to create a special user for doc builds but that’s beyond the scope of this release.
* Refactor Ini.pm to facilitate testing.
* Complete statement/branch coverage for Ini.pm.
* Improved functions used to test/munge manifest and info files.
* Full coverage is verified when specified.
* Modules marked with partial coverage will error if they are actually fully covered.
* Simplified test representation is DefineTest.
* Added new representation for queries in DefineTest and added API functions.
* Update modules using DefineTest to use new API.
* Fixed an issue where read-only operations that used local worker processes (i.e. restore) were creating write locks that could interfere with parallel archive-push. (Reported by Jens Wilke.)

The stanza-upgrade command provides a mechanism for upgrading a stanza after upgrading to a new major version of PostgreSQL.

Bug Fixes:
* Fixed an issue where tables over 1GB would report page checksum warnings after the first segment. (Reported by Stephen Frost.)
* Fixed an issue where databases created with a non-default tablespace would raise bogus warnings about pg_filenode.map and pg_internal.init not being page aligned. (Reported by blogh.)
Refactoring:
* Improved the code and tests for fileManifest() to prevent a possible race condition when files are removed by the database while the manifest is being built.
* Automated builds of Debian packages for all supported distributions.
* Added --dev option to aggregate commonly used dev options.
* Added --no-package option to skip package builds.
* C library and packages are built by default, added -smart option to rebuild only when file changes are detected.
* The --libc-only option has been changed to --build-only now that packages builds have been added.
Bug Fixes:
* Fixed a regression introduced in v1.13 that could cause backups to fail if files were removed (e.g. tables dropped) while the manifest was being built. (Reported by Navid Golpayegani.)
Refactoring:
* Refactor FileCommon::fileManifest() and FileCommon::fileStat to be more modular to allow complete branch/statement level coverage testing.
