4d9920cc48 Fix null and linefeed handling in Db->executeSql().
The join() used was not able to handle nulls and was replaced by a loop.  An injudicious trim was removed when the source of extra linefeeds was determined to be an additional loop execution that was not handled correctly.

0c320e7df7 Allow selective restore of databases from a cluster backup.
This feature can result in major space and time savings when only specific databases are restored. Unrestored databases will not be accessible but must be manually dropped before they will be removed from the shared catalogue.

e430f0a054 Added --db-version=minimal option as default.
This change assigns each version of PostgreSQL to a specific OS version for testing to minimize the number of tests being run.  In general, older versions of PostgreSQL are assigned to older OS versions.

The old behavior can be enabled with `--db-version=all`.

a6a19e3735 Test directories are now located on the host VM rather than in the Docker container.
This change allows for easier testing since all files are local on the host VM and can be easily accessed without using `docker exec`.  In addition, this change is required to allow multiple Docker containers per test case which is coming soon.

ed20c2eda3 Close #172: Unable to unpack Int64 when running on 32-bit OS
Added a note to documentation that only 64-bit distributions are supported.  It seems unlikely that anybody would be running a production server on anything else these days so we'll wait for a field report before taking further action.

9ab0dd80f7 v1.00: New Repository Format and Configuration Scheme, Link Support
* This flag day release breaks compatibility with older versions of pgBackRest. The manifest format, on-disk structure, configuration scheme, and the exe/path names have all changed. You must create a new repository to hold backups for this version of pgBackRest and keep your older repository for a time in case you need to do a restore. Restores from the prior repository will require the prior version of pgBackRest but because of name changes it is possible to have 1.00 and a prior version of pgBackRest installed at the same time. See the notes below for more detailed information on what has changed.

* Implemented a new configuration scheme which should be far simpler to use. See the User Guide and Configuration Reference for details but for a simple configuration all options can now be placed in the stanza section. Options that are shared between stanzas can be placed in the [global] section. More complex configurations can still make use of command sections though this should be a rare use case.

* The repo-path option now always refers to the repository where backups and archive are stored, whether local or remote, so the repo-remote-path option has been removed. The new spool-path option can be used to define a location for queueing WAL segments when archiving asynchronously. A local repository is no longer required.

* The default configuration filename is now pgbackrest.conf instead of pg_backrest.conf. This was done for consistency with other naming changes but also to prevent old config files from being loaded accidentally when migrating to 1.00.

* The default repository name was changed from /var/lib/backup to /var/lib/pgbackrest.

* Lock files are now stored in /tmp/pgbackrest by default. These days /run/pgbackrest is the preferred location but that would require init scripts which are not part of this release. The lock-path option can be used to configure the lock directory.

* Log files are now stored in /var/log/pgbackrest by default and no longer have the date appended so they can be managed with logrotate. The log-path option can be used to configure the lock directory.

* Executable filename changed from pg_backrest to pgbackrest.

* All files and directories linked from PGDATA are now included in the backup. By default links will be restored directly into PGDATA as files or directories. The --link-all option can be used to restore all links to their original locations. The --link-map option can be used to remap a link to a new location.

* Removed --tablespace option and replaced with --tablespace-map-all option which should more clearly indicate its function.

* Added detail log level which will output more information than info without being as verbose as debug.

885797e4b5 Migrated many functions from File.pm to FileCommon.pm.
This makes make the migrated file functions available to parts of the code that don't have access to a File object.  They still exist as wrappers in the File object to support remote calls.

0e4fdda6d8 Improved error handling when remote closes unexpectedly.
In conditions where an error is known to have occurred wait to try and capture the error in the first call that detects the error.  Due to timing sometimes the error could be caught later, which worked, but it made the functionality inconsistent in testing.

5307c858a7 v0.92: Command-line Repository Path Fix
* 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.  Reported by Jan Wieck.

aea14c8553 v0.91: Tablespace Bug Fix and Minor Enhancements
* **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.

0b317d9040 Fix minor bug in protocol compression.
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.

631535ae4f v0.90: 9.5 Support, Various Enhancements, and Minor Bug Fixes
* 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.

f8b47997a3 Closed #127: More sanity checking for --delta restores
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.

5c815e4fc0 Closed #58: Get catalog number for better tablespace copying
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 `--delta` restore. This only applies to PostgreSQL >= 9.0 -- before that only one PostgreSQL version could use a tablespace.
