Fixed an issue where the master process was passing --repo-remote-path instead of --repo-path to the remote and causing the lock files to be created in the default repository directory (/var/lib/backup), generally ending in failure. This was only an issue when --repo-remote-path was defined on the command line rather than in pg_backrest.conf.
* **IMPORTANT BUG FIX FOR TABLESPACES**: A change to the repository format was accidentally introduced in 0.90 which means the on-disk backup was no longer a valid PostgreSQL cluster when the backup contained tablespaces. This only affected users who directly copied the backups to restore PostgreSQL clusters rather than using the restore command. However, the fix breaks compatibility with older backups that contain tablespaces no matter how they are being restored (pgBackRest will throw errors and refuse to restore). New full backups should be taken immediately after installing version 0.91 for any clusters that contain tablespaces. If older backups need to be restored then use a version of pgBackRest that matches the backup version. _Reported by Evan Benoit_.
* Copy global/pg_control last during backups.
* Write .info and .manifest files to temp before moving them to their final locations and fsync'ing.
* Rename --no-start-stop option to --no-online.
* Static source analysis using Perl-Critic, currently passes on gentle.
This erroneous last caused a warning (which threw an error) and masked the error in decompression. It was found when accidentally attempting to decompress an already-decompressed file, so not a big deal in practice which is probably why it hug around for so long.
Perl Critic added and passes on gentle. A policy file has been created with some permanent exceptions and a list of policies to be fixed in approximately the order they should be fixed in.
* Fixed an issue where specifying --no-archive-check would throw a configuration error. Reported by Jason O'Donnell.
* Fixed an issue where a temp WAL file left over after a well-timed system crash could cause the next archive-push to fail.
* Fixed an issue where document generation failed because some OSs are not tolerant of having multiple installed versions of PostgreSQL. A separate VM is now created for each version. Also added a sleep after database starts during document generation to ensure the database is running before the next command runs. Reported by John Harvey.
* The retention-archive option can now be be safely set to less than backup retention (retention-full or retention-diff) without also specifying archive-copy=n. The WAL required to make the backups that fall outside of archive retention consistent will be preserved in the archive. However, in this case PITR will not be possible for the backups that fall outside of archive retention.
* When backing up and restoring tablespaces pgBackRest only operates on the subdirectory created for the version of PostgreSQL being run against. Since multiple versions can live in a tablespace (especially during a binary upgrade) this prevents too many files from being copied during a backup and other versions possibly being wiped out during a restore. This only applies to PostgreSQL >= 9.0 -- prior versions of PostgreSQL could not share a tablespace directory.
* Generate an error when archive-check=y but archivecommand does not execute pgbackrest. Contributed by Jason O'Donnell.
* Improved error message when repo-path or repo-remote-path does not exist.
* Added checks for --delta and --force restore options to ensure that the destination is a valid $PGDATA directory. pgBackRest will check for the presence of PGVERSION or backup.manifest (left over from an aborted restore). If neither file is found then --delta and --force will be disabled but the restore will proceed unless there are files in the $PGDATA directory (or any tablespace directories) in which case the operation will be aborted.
* When restore --set=latest (the default) the actual backup restored will be output to the log.
* Support for PostgreSQL 9.5 partial WAL segments and recoverytargetaction setting. The archivemode = 'always' setting is not yet supported.
* Support for recoverytarget = 'immediate' recovery setting introduced in PostgreSQL 9.4.
* The following tablespace checks have been added: paths or files in pgtblspc, relative links in pgtblspc, tablespaces in $PGDATA. All three will generate errors.
Added checks for `--delta` and `--force` restore options to ensure that the destination is a valid $PGDATA directory. pgBackRest will check for the presence of `PG_VERSION` or `backup.manifest` (left over from an aborted restore). If neither is found then `--delta` and `--force` will be disabled but the restore will proceed unless there are files in the $PGDATA directory (or any tablespace directories) in which case the operation will be aborted.

Since multiple versions can live in a tablespace (especially during a binary upgrade) this prevents too many files from being copied during a backup and other versions possibly being wiped out during a `--delta` restore. This only applies to PostgreSQL >= 9.0 -- before that only one PostgreSQL version could use a tablespace.

Also added a sleep after database starts during document generation to ensure the database is running before the next command runs.

1) Tests for all operating systems can now be run with a single command.
2) Tests can be run in parallel with --process-max.
3) Container generation now integrated into test.pl
4) Some basic test documentation.
* Fixed an issue where longer-running backups/restores would timeout when remote and threaded. Keepalives are now used to make sure the remote for the main process does not timeout while the thread remotes do all the work. The error message for timeouts was also improved to make debugging easier.
* Allow restores to be performed on a read-only repository by using --no-lock and --log-level-file=off. The --no-lock option can only be used with restores.
* Minor styling changes, clarifications and rewording in the user guide.
* The dev branch has been renamed to master and for the time being the master branch has renamed to release, though it will probably be removed at some point -- thus ends the gitflow experiment for pgBackRest. It is recommended that any forks get re-forked and clones get re-cloned.
