1. Introduction Postgres-BDR (or just BDR, for short) is an open source project from 2ndQuadrant that provides multi-master features for PostgreSQL.

Transaction traceability in PostgreSQL 10 with txid_status(…)

September 26, 2017/1 Comment/in Craig's PlanetPostgreSQL /by craig.ringer

One feature quietly added to PostgreSQL 10 is the ability to determine the commit status of any transaction by transaction-id. It’s reasonable to wonder why you’d want this, since you know if you committed the transaction, it’s still in progress, or if you or rolled it back. And you can check for in-progress transactions in […]

PG Phriday: pglogical and Postgres 10 Partitions

September 22, 2017/6 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: […]

PostgreSQL 10 Logical Replication with OmniDB

September 19, 2017/0 Comments/in OmniDB, William's PlanetPostgreSQL /by William Ivanski

1. Introduction Logical replication uses a publish/subscribe model and so we create publications on the upstream (or publisher) and subscriptions on downstream (or subscriber). For more details about it, please refer to this blog post from my colleague Petr Jelinek, and also to the PostgreSQL documentation. Here we will show how to build a test […]

PG Phriday: Crazy Correlated Column Crusade

July 14, 2017/4 Comments/in Shaun's PlanetPostgreSQL /by Shaun Thomas

For a long time, the Postgres query planner has sported a huge blinking neon blind-spot that frustrated and enraged DBAs throughout the universe to a level just shy of murderous frenzy. How is this even possible? What terrible lurking horror could elicit such a visceral response from probably the most boring and straight-laced people ever […]

News and Roadmap from Postgres-XL 10

July 5, 2017/6 Comments/in 2ndQuadrant, Pavan's PlanetPostgreSQL /by Pavan Deolasee

We expect Postgres-XL 10 to be released in the next few months, with the new features of partitioning and logical replication. You’ll be able to load Postgres-XL directly from PostgreSQL. For the first time, you’ll be able to run massively parallel queries both across the datanodes and within the datanodes to give huge performance gains. […]

More robust collations with ICU support in PostgreSQL 10

May 22, 2017/20 Comments/in Eisentraut's PlanetPostgreSQL, PostgreSQL /by Peter Eisentraut

In this article, I want to introduce the ICU support in PostgreSQL, which I have worked on for PostgreSQL version 10, to appear later this year. Sorting Sorting is an important functionality of a database system. First, users generally want to see data sorted. Any query result that contains more than one row and is […]

Logical Replication in PostgreSQL 10

April 28, 2017/37 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 […]
