PG Phriday: BDR Around the Globe

May 4, 2018/2 Comments/in Shaun's PlanetPostgreSQL /by Shaun Thomas

With the addition of logical replication in Postgres 10, it’s natural to ask “what’s next”? Though not directly supported yet, would it be possible to subscribe two Postgres 10 nodes to each other? What kind of future would that be, and what kind of scenarios would be ideal for such an arrangement? As it turns […]

Near-Zero Downtime Automated Upgrades of PostgreSQL Clusters in Cloud (Part II)

April 30, 2018/0 Comments/in 2ndQuadrant, DevOps, Featured, Gulcin's PlanetPostgreSQL, pglogical, PostgreSQL /by Gulcin Yildirim

I’ve started to write about the tool (pglupgrade) that I developed to perform near-zero downtime automated upgrades of PostgreSQL clusters. In this post, I’ll be talking about the tool and discuss its design details. You can check the first part of the series here: Near-Zero Downtime Automated Upgrades of PostgreSQL Clusters in Cloud (Part I). The tool is […]

Near-Zero Downtime Automated Upgrades of PostgreSQL Clusters in Cloud (Part I)

March 23, 2018/5 Comments/in 2ndQuadrant, DevOps, Featured, Gulcin's PlanetPostgreSQL, pglogical, PostgreSQL /by Gulcin Yildirim

Last week, I was at Nordic PGDay 2018 and I had quite a few conversations about the tool that I wrote, namely pglupgrade, to automate PostgreSQL major version upgrades in a replication cluster setup. I was quite happy that it has been heard and some other people in different communities giving talks at meetups and other […]

PG Phriday: pglogical and Postgres 10 Partitions

September 22, 2017/5 Comments/in pglogical, Shaun's PlanetPostgreSQL /by Shaun Thomas

During the Postgres Open 2017 conference in San Francisco, someone came to the 2ndQuadrant booth and struck up a conversation with me. During our shameless geeking out over database mechanics, he asked me if pglogical supported the new Postgres 10 partitions. Given my noted expertise in all things Postgres, I answered in the appropriate manner: […]

Logical Replication in PostgreSQL 10

April 28, 2017/33 Comments/in Petr's PlanetPostgreSQL /by Petr Jelinek

PostgreSQL 10 is getting close to its first beta release and it will include the initial support for logical replication, which is was written primarily by me and committed by my colleague Peter Eisentraut, and is internally based on the work 2ndQuadrant did on pglogical (even though the user interface is somewhat different). I’d like […]

Re-import repository keys for BDR and pglogical apt repositories

March 23, 2017/2 Comments/in Craig's PlanetPostgreSQL /by craig.ringer

The BDR and pglogical apt repository GnuPG signing keys have been renewed. Users should re-import the existing keys. You can verify that it’s still the same key as referenced in the documentation, just with a later expiry date. Simply run: wget –quiet -O – http://packages.2ndquadrant.com/bdr/apt/AA7A6805.asc | sudo apt-key add – sudo apt-key finger AA7A6805 | […]

pglogical 1.2 with PostgreSQL 9.6 support

October 20, 2016/0 Comments/in Petr's PlanetPostgreSQL /by Petr Jelinek

PostgreSQL 9.6 is now out and so is an updated version of pglogical that works with it. For quick guide on how to upgrade the database with pglogical you can check my post which announced 9.6beta support. The main change besides the support for 9.6.x release of PostgreSQL is in the way we handle the […]

BDR History and future

October 18, 2016/0 Comments/in Craig's PlanetPostgreSQL /by craig.ringer

BDR is both a patch to PostgreSQL core and an extension on top of PostgreSQL core. How did that come about, and what’s it’s future? Development of BDR was initiated around the time PostgreSQL 9.2 was in development. Arguably earlier if you count things like the extension mechanism. The goal of BDR is, and has […]

BDR is coming to PostgreSQL 9.6

September 21, 2016/39 Comments/in Craig's PlanetPostgreSQL /by craig.ringer

I’m pleased to say that Postgres-BDR is on its way to PostgreSQL 9.6, and even better, it works without a patched PostgreSQL. BDR has always been an extension, but on 9.4 it required a heavily patched PostgreSQL, one that isn’t fully on-disk-format compatible with stock community PostgreSQL 9.4. The goal all along has been to […]

Thoughts on Uber’s List of Postgres Limitations

August 2, 2016/8 Comments/in 2ndQuadrant, Simon's PlanetPostgreSQL /by Simon Riggs

An Uber technical blog of July 2016 described the perception of “many Postgres limitations”. Regrettably, a number of important technical points are either not correct or not wholly correct because they overlook many optimizations in PostgreSQL that were added specifically to address the cases discussed. In most cases, those limitations were actually true in the […]
