Amazon RDS now supports PostgreSQL 9.6.1

Noticias PostgreSQL [ENG] - Vie, 11/11/2016 - 01:00

Amazon RDS for PostgreSQL now supports the next major release of the PostgreSQL open source database, version 9.6.1. New features include parallel query, phrase search, and improvements to performance and usability. With this release, Amazon RDS for PostgreSQL also supports the bloom and pg_visibility extensions.

You can create a new Amazon RDS for PostgreSQL 9.6.1 database instance with just a few clicks from the AWS Management Console or you can upgrade an existing PostgreSQL 9.5 database instance using point-and-click upgrade. Upgrading from version 9.3 and 9.4 requires you to perform a point-and-click upgrade to the next major version, reaching version 9.5 before upgrading to 9.6.1. Each upgrade operation involves a short period of unavailability for your database instance. Learn more about upgrading your database instances from the Amazon RDS User Guide.

pgBackRest 1.09 Released

Noticias PostgreSQL [ENG] - Mar, 01/11/2016 - 01:00

November 1, 2016: Crunchy Data is proud to announce pgBackRest 1.09, Reliable PostgreSQL Backup & Restore.

Release 1.09

Since 1.0 we have improved scalability, added backup from a standby, selective restore, and support for the 9.6 non-exclusive backup method. All the major new features since 1.0 are detailed below.

Links New Features Improved Multi-Processing Scalability

Converted Perl threads to child processes to improve compatibility and greatly increase scalability. 3TB/hour backup speeds can be achieved with 32 cores and 10GbE, including compression and checksums.

Backup from a Standby Cluster

Performing backups on a standby host greatly reduces CPU and IO load on the master host. pgBackRest copies the majority of the files from the standby and only a few from the master, while still producing a backup exactly as if it were performed entirely on the master.

Selective Restore

Selected databases can be restored from a cluster backup to save space when not all the databases are required. WAL replay during restore takes place for all databases so some space will be used, but generally far less than if the unneeded databases were restored completely. After recovery completes the unrestored databases will not be accessible but can be dropped in the usual way.

Non-Exclusive Backups

Support for non-exclusive backups in PostgreSQL 9.6.

Directory/File Exclusions

Exclude directories during backup that are cleaned, recreated, or zeroed by PostgreSQL at startup. These include pgsql_tmp and pg_stat_tmp. The postgresql.auto.conf.tmp file is now excluded in addition to files that were already excluded: backup_label.old, postmaster.opts, postmaster.pid, recovery.conf, recovery.done.

Exclude contents of $PGDATA/pg_replslot directory so that replication slots on the master do not become part of the backup.

Enhanced Info Command

Enhanced text output of info command to include timestamps, sizes, and the reference list for all backups.

Check Command

Added check command to validate that pgBackRest is configured correctly for archiving and backups.

Flexible Configuration

More flexible configuration for databases. Master and standby can both be configured on the backup server and pgBackRest will automatically determine which is the master. This means no configuration changes for backup are required after failing over from a master to standby when a separate backup server is used.

About

pgBackRest aims to be a simple, reliable backup and restore system that can seamlessly scale up to the largest databases and workloads. Instead of relying on traditional backup tools like tar and rsync, pgBackRest implements all backup features internally and uses a custom protocol for communicating with remote systems. Removing reliance on tar and rsync allows for better solutions to database-specific backup challenges. The custom remote protocol allows for more flexibility and limits the types of connections that are required to perform a backup which increases security.

Crunchy Data supports the ongoing and active development of pgBackRest as an entirely open source project, released under the BSD-compatible MIT license.

PostgreSQL Magazine presents : The Paper Elephant #01

Noticias PostgreSQL [ENG] - Mar, 01/11/2016 - 01:00

The PostgreSQL Magazine project is back with an original concept named The Paper Elephant : a folded newspaper with a dynamic look & feel.

As always the content comes directly from the community ! In this first issue, we gathered articles from key members of the PostgreSQL project: Josh Berkus talks about the new version numbering scheme,
Hans-Jürgen Schönig writes about performance and Craig Kierstens an overview of JSON, JSONB and hstore. You'll also find an interview of Paul Ramsey from the PostGIS project.

The Paper Elephant is an independent media edited by and for the PostgreSQL Community. This issue was created with the financial help of PostgreSQL Europe and many benevolent contributors ( witers, editors, reviewers ). Kudos to all of them.

Just like the name says, The Paper Elephant is a "paper first" media: it is designed to be printed out and distributed during events (conferences, meetups, etc.) to promote PostgreSQL.

The first edition will be available at PostgreSQL Conference Europe 2016, Paris Open Source Summit 2016 and FOSDEM 2017. If you want to distribute the magazine at a local IT event, please Contact Us !

If you want a glimpse of the newspaper, you can download the PDF version here: http://pgmag.org/download

PostgreSQL 9.6.1, 9.5.5, 9.4.10, 9.3.15, 9.2.19 and 9.1.24 Released!

Noticias PostgreSQL [ENG] - Jue, 27/10/2016 - 01:00

The PostgreSQL Global Development Group has released an update to all supported versions of our database system, including 9.6.1, 9.5.5, 9.4.10, 9.3.15, 9.2.19, and 9.1.24. This is also the last update for the PostgreSQL 9.1 series as it is now end-of-life. This release fixes two issues that can cause data corruption, which are described in more detail below. It also patches a number of other bugs reported over the last three months. The project urges users to apply this update at the next possible downtime.

WAL-logging of truncated relations

Prior to this release, there was a chance that a PostgreSQL instance would try to access data that no longer existed on disk. If the free space map was not updated to be aware of the truncation, a PostgreSQL database could return a page that was already truncated and produce an error such as:

ERROR: could not read block 28991 in file "base/16390/572026": read only 0 of 8192 bytes

If checksumming is enabled, checksum failures in the visibility map could also occur.

This issue is present in the 9.3, 9.4, 9.5, and 9.6 series of PostgreSQL releases.

pg_upgrade issues on big-endian machines

On big-endian machines (e.g. many non-Intel CPU architectures), pg_upgrade would incorrectly write the bytes of the visibility map leading to pg_upgrade failing to complete.

If you are using a big-endian machine (many non-Intel architectures are big-endian) and have used pg_upgrade to upgrade from a pre-9.6 release, you should assume that all visibility maps are incorrect and need to be regenerated. It is sufficient to truncate each relation's visibility map with contrib/pg_visibility's pg_truncate_visibility_map() function. Please read the "Updating" section for post-installation instructions on how to resolve this issue on your PostgreSQL instances.

This issue is present only in the PostgreSQL 9.6.0 release.

Bug Fixes and Improvements

In addition to the above, this update also fixes a number of bugs reported in the last few months. Some of these issues affect only the 9.6 series, but many affect all supported versions. There are more than 50 fixes provided in this release, including:

  • Fix use-after-free hazard in execution of aggregate functions using DISTINCT, which could lead to crashes
  • Fix incorrect handling of polymorphic aggregates used as window functions, which could lead to crashes
  • Fix incorrect creation of GIN index WAL records on big-endian machines
  • Fix file descriptor leakage when truncating a temporary relation of more than 1GB
  • Fix query-lifespan memory leak in a bulk UPDATE on a table with a PRIMARY KEY or REPLICA IDENTITY index
  • Fix SELECT FOR UPDATE/SHARE to correctly lock tuples that have been updated by a subsequently-aborted transaction
  • Fix COPY with a column name list from a table that has row-level security enabled
  • Fix deletion of speculatively inserted TOAST tuples when backing out of INSERT ... ON CONFLICT
  • Fix timeout length when VACUUM is waiting for exclusive table lock so that it can truncate the table
  • Fix bugs in merging inherited CHECK constraints while creating or altering a table
  • Fix replacement of array elements in jsonb_set()
  • Fix possible sorting error when aborting use of abbreviated keys in btree indexes
  • On Windows, retry creation of the dynamic shared memory control segment after an access-denied error
  • Fix pgbench's calculation of average latency
  • Make pg_receivexlog work correctly with --synchronous without slots
  • Make pg_rewind turn off synchronous_commit in its session on the source servere
  • Don't try to share SSL contexts across multiple connections in libpq
  • Support OpenSSL 1.1.0
  • Install TAP test infrastructure so that it's available for extension testing
  • Several fixes for logical WAL decoding and replication slots
  • Several fixes for minor issues in pg_dump, pg_xlogdump, and pg_upgrade
  • Several fixes for minor issues in the query planner and in the output of EXPLAIN
  • Several fixes for timezone support

This update also contains tzdata release 2016h for DST law changes in Palestine and Turkey, plus historical corrections for Turkey and some regions of Russia. Switch to numeric abbreviations for some time zones in Antarctica, the former Soviet Union, and Sri Lanka.

The IANA time zone database previously provided textual abbreviations for all time zones, sometimes making up abbreviations that have little or no currency among the local population. They are in process of reversing that policy in favor of using numeric UTC offsets in zones where there is no evidence of real-world use of an English abbreviation. At least for the time being, PostgreSQL will continue to accept such removed abbreviations for timestamp input. But they will not be shown in the pg_timezone_names view nor used for output.

In this update, AMT is no longer shown as being in use to mean Armenia Time. Therefore, we have changed the Default abbreviation set to interpret it as Amazon Time, thus UTC-4 not UTC+4.

EOL Notice for Version 9.1

PostgreSQL version 9.1 is now End-of-Life (EOL). No additional updates or security patches will be released by the community for this version. Users still on 9.1 are urged to upgrade as soon as possible. See our Versioning Policy (https://www.postgresql.org/support/versioning/) for more information.

Updating

All PostgreSQL update releases are cumulative. As with other minor releases, users are not required to dump and reload their database or use pg_upgrade in order to apply this update release; you may simply shut down PostgreSQL and update its binaries.

If your system was affected by the big-endian pg_upgrade bug, please read Visibility Map Problems and follow the instructions on how to fix your this issue on your PostgreSQL instances.

Users who have skipped one or more update releases may need to run additional, post-update steps; please see the release notes for earlier versions for details.
