Neues vom PostgreSQL Planet
PostgreSQL 12 is available as binary package on FreeBSD, but not in the quarterly update.
Recently we published a blog about a very simple application failover using libpq features which could be the simplest of all automatic application connection routing. In this blog post, we are discussing how a proxy server using HAProxy can be used for connection routing which is a well-known technique with very wide deployment.
Some weeks ago, in the light of PostgreSQL v12 release, I wrote a general overview on various major version upgrade methods and benefits of upgrading in general – so if upgrading is a new thing for you I’d recommend to read that posting first. But this time I’m concentrating on the newest (available since v10) and the most complex upgrade method – called “Logical Replication” or LR shortly.
My very simple attempt at keeping PostgreSQL up-to-date on FreeBSD machines.Installing PostgreSQL on FreeBSD via Ansible
I’m slowly moving to Ansible to manage my machines, and one problem I’m trying to solve at best is how to keep PostgreSQL up-to-date.
In the case of FreeBSD machines, pkgng is the module to use, but in the past I was used to this very simple playbook snippet:
PostgreSQL is a widely-used Open Source database and has been ranked # 1 for the past 2 years in DB-Engine rankings. As such, there is always a need for reliable and robust monitoring solutions. While there are some commercial monitoring tools, there is an equally good number of open source tools available for monitoring PostgreSQL.
I’ve been to a lot of conferences over the years. PgConf EU, PostgresOpen, too many pgDays to count, and even more none Postgres conferences (OSCON, Strangeloop, Railsconf, PyCon, LessConf, and many more). I’ve always found Postgres conferences one of the best places to get training and learn about what’s new with Postgres (in addition to Dimitri’s recent book, more on that below).

cary huang: Vancouver Postgres Group Meetup Event – Kubernetes Best Practices for Distributed SQL databases
Date: October 24, 2019
Guest Speaker: Andrew Nelson, Developer Advocate from YugaByteAbout Vancouver Postgres User Meetup Group
Vancouver Postgres is a Postgres user meetup group based in Vancouver, Canada. It specializes in building Postgres users to the related ecosystem including but not limited to technologies such as RDS Postgres, Aurora for Postgres, Google Postgres, PostgreSQL.Org Postgres, Greenplum, Timescale and ZomboDB.
A few days ago we added the option to suggest you changes to your PATH to prevent version clashes.pgenv: adjust your PATH!
In the following you can find another quick video that demonstrate how easy it is to get, almost automtically, a PostgreSQL 12 instance up and running on your local machine using pgenv.
To use these, copy the files into your PostgreSQL 12 Windows 64-bit install folders in same named folders and then run CREATE EXTENSION as usual in the databases of your choice. More details in the packaged README.txt
When you build replication in PostgreSQL using Streaming replication, you cannot perform writes to a standby node; only reads. This way, you could offload reads or reporting queries to standby servers and send writes to master. Additionally, starting from PostgreSQL 10,
Registration for pgDay Paris 2020 is now open.
We have some new ticket types this year, including a very cheap BLIND ticket that is only sold until the schedule is published. If you know you are coming to the conference no matter what, hurry up and grab one of these!
We also have cheap tickets this year for students and the unemployed. Valid proof is required.

“Durability”, the D of ACID, demands that a committed database transaction remains committed, no matter what. For normal outages like a power failure, this is guaranteed by the transaction log (WAL). However, if we want to guarantee durability even in the face of more catastrophic outages that destroy the WAL, we need more advanced methods.
This article discusses how to use pg_receivewal to maintain durability even under dire circumstances.
The call for papers for pgDay Paris 2020 is now open. Submit your proposals for interesting talks about all things PostgreSQL, and join us in March!
