PostgreSQL Popularity Continues to Grow!

Simon's PlanetPostgreSQL
Some years ago, I prophesized that PostgreSQL would win in the end, and that we would be able to tell because there would be "Microsoft PostgreSQL".I am happy to report that has now happened. Microsoft PostgreSQL database service on Azure was announced recently.Of course, that was just a metaphor for "a.n.other big company", I'm not signalling MS as requiring special attention here, in fact they have been the last to do this.That means PostgreSQL database services are now available from all of the main cloud service providers: Amazon, Google, IBM and Microsoft. Yay! We have achieved 100% breakthrough in terms of cloud adoption - everyone recognizes now that PostgreSQL is big and adoption is accelerating.PostgreSQL is now used in UK and US governments, see UK (

Kanban & devops culture at 2ndQuadrant – Part 2

In Part 2 of this series, we will continue our journey within the developmental dynamics of the Barman open source project for PostgreSQL database backup and disaster recovery. After providing a small introduction to devops and Kanban in Part 1, let's focus on the basic element of our daily management: The Boards.(more…)

“Now is Better Than Never” – Why I decided to attend PyCon8…

2ndQuadrant, Britt's PlanetPostgreSQL
…and why I’m glad I did.It’s not all technical… Who knew?!Last year, Pycon7 was held right about the time I joined 2ndQuadrant. Seeing as I was new to the technology AND the Italian language (note: there was an English track), I opted out of attending. Well, after attending Pycon8, I can say that I won’t make that mistake again!Over the past year working in the Open Source community, I’ve learned more technical information than I could have ever imagined. Even then, attending a technical conference and understanding (completely) technical talks seemed a little far-fetched. Or so I thought!Since being introduced to the wonderful world of Open Source, PostgreSQL, and numerous other technologies - I’m continuously fascinated by the way that the communities intertwine.

Barman 2.1 and the new –archive option

Giulio's PlanetPostgreSQL
Barman 2.1 Version 2.1 of Barman, backup and recovery manager for PostgreSQL, was released Thursday, Jan. 5.The new release, along with several bugfixes, introduces preliminary support for the upcoming PostgreSQL 10, and adds the --archive option to the switch-xlog command. switch-xlog --archive The new --archive option is especially useful when setting up a new server.Until now, the switch-xlog command used to force the PostgreSQL server to switch to a different transaction log file. Now, Barman also gives the --archive option, which triggers WAL archiving after the xlog switch, and forces Barman to wait for the archival of the closed WAL file.By default Barman expects to receive the WAL in 30 seconds, the amount of seconds to wait can be changed using the --archive-timeout...

PGDay.IT 2016 in Prato, Italy

2ndQuadrant, Jonathan's PlanetPostgreSQL
This year, the ITPUG (Italian Postgres User Group) organized PGDay in Prato, my hometown and city where the association was born, although most of the members are from outside of the Tuscany region.It was my pleasure to contribute to the community by sharing my professional experience. I gave a talk about PostgreSQL on Network File System, a research based on crash tests to prove reliability using PostgreSQL on NFS. Sharing my PostgreSQL experience with the participants was useful and pleasant.During the event, I had the chance to attend the talk about tools for upgrading Postgres between major releases given by Denis Gasparin; and the one about ULSS's (Regional Healthcare System) migration to Open Source, given by Giorgio Roncolato, proving that more institutions than we thought a

The PostgreSQL License – What Does It Mean For My Business?

Umair's PlanetPostgreSQL
When I talk to various people about PostgreSQL, based on where they are in the process of analyzing it, I get asked many similar questions. One of the most frequently asked questions is: What is the PostgreSQL licensing model? Here is my attempt to address this question from the perspective of what the PostgreSQL license means for your business. Go Ahead, Read It - It’s Really Not That Scary Let’s be honest with ourselves, we are really not in the habit of reading license agreements - they are best left to the legal department to decipher. And seriously, licenses have become so complex and so detailed that even if I try really really hard to read just a few clauses, my head starts to hurt.The PostgreSQL License is different though.I have reproduced the license in full at the e

Load data in Postgres-XL at over 9M rows/sec

2ndQuadrant, Pavan's PlanetPostgreSQL
We are faced with this question: “What’s the ingestion rate of Postgres-XL?”, and I realised I don’t have a very good answer to that. Since recently we made some good improvements in this area, I was curious to know too. Well, I decided to benchmark. Hardware and Software For the tests, I used a Postgres-XL cluster running on EC2 instances. Since COPY has to go through the coordinator, it seemed reasonable to use a compute-optimised c3.8xlarge instance for running coordinator. Similarly, for datanodes,  storage-optimised i2.xlarge instances are more appropriate. Both these instances have attached SSD disks, though i2.xlarge instance has more storage than the c3.8xlarge instance. So the next question was how to generate data for the test? We’d used TPC-H benchmark for previous perform
