Preamble How many current Barman users have thought about saving backups in a remote destination in the cloud? How many have thought about taking that backup directly from the PostgreSQL server itself? Well, since Barman 2.10 this is now possible! How? Let’s discover that together in the following articles.
PostgreSQL 12 contains two new server settings: ssl_min_protocol_version ssl_max_protocol_version As the names indicate, these are used to control the oldest (minimum) and newest (maximum) version of the SSL and TLS protocol family that the server will accept. (For historical reasons, in PostgreSQL, all settings related to SSL and TLS are named ssl_something, even though TLS […]
Securing data in motion is a necessity in today’s world. PostgreSQL provides a way to encrypt and authenticate communication by using a Secure Sockets Layer or SSL protocol. 2ndQuadrant hosted a webinar to give an introduction on using SSL, encryption and authentication methods, and how to successfully configure and deploy SSL with PostgreSQL. The webinar […]
K-nearest neighbor answers the question of “What is the closest match?”. PostgreSQL 12 can answer this question, and use indexes while doing it.
With the recent release of PostgreSQL 12, there’s been a lot of interest in the latest version and by popular demand, the team at 2ndQuadrant organized a live webinar on “PostgreSQL Partitioning”. The webinar was hosted by Simon Riggs, CTO 2ndQuadrant, who gave an overview of PostgreSQL partitioning features and how they play a key […]
In the past year, I have had many conversations with many clients and prospects about Postgres-BDR. For those of you who don’t know this Postgres-BDR has been in production for many mission critical deployments for quite some time. We have more clients coming on board each month. Most recently, I have been meeting with […]
I have written about managing a PostgreSQL commitfest before. During the PostgreSQL 13 development cycle, I did it again. This time I used a different strategy, mostly because I felt that there was excessive accumulation of very old patches that had received insufficient attention. So apart from bugfixes (which are always special cases), I focused […]
Now that PostgreSQL 12 is out, we consider foreign keys to be fully compatible with partitioned tables. You can have a partitioned table on either side of a foreign key constraint, and everything will work correctly. Why do I point this out? Two reasons: first, when partitioned tables were first introduced in PostgreSQL 10, they […]
The new PostgreSQL 12 release is just around the corner and by popular demand, the team at 2ndQuadrant hosted “New Features in Postgres 12″ webinar. The 1 hour + long session, conducted by Peter Eisentraut (Core Team Member of the PostgreSQL Project), gave an in-depth preview of everything new in PostgreSQL 12, improvements to partitioning, generated […]
With every new release of PostgreSQL, there are a range of performance enhancements. Some are system-wide and affect every user, but most are highly specific to a certain use case. In this post, I am going to briefly highlight three improvements in PG12 that speed up certain operations. 1. Minimal decompression of TOAST values TOAST […]
