oded valin: SQL Optimization: a comprehensive developer’s guide
Ok you got a database, how do you optimize SQL performances? To answer this question you need a lot of time and effort in order to understand workloads and performance patterns, evaluate degradation and apply corrective measures. However there are standard practices that you can implement to improve performances. This SQL optimization guide will showcase some best practices that apply across almost every database and can be a good starting point to optimize your database workloads.
Henrietta Dombrovskaya: Logging: What, Why and When
There are multiple PostgreSQL configuration parameters that determine what exactly to log. In Postgres 16, there are 30 of them if you exclude the ones related to the file naming and location. We rarely change them when we create a new instance. In a best-case scenario, your organization has a default set of cnfiguration parameters which are applied when a new instance is created.
Andrew Atkinson: Maintainable Podcast — Maintainable…Databases? 🎙️
Recently I appeared as a guest on the Maintainable Podcast with Robby Russell. I’ve admired this podcast for a long time based on the guests, conversations, and focus on software maintenance.
Much of what a software engineer does is evolve and maintain existing systems. I’m glad Robby created this podcast to explore maintenance topics, and has gathered the perspectives of many practitioners.
What is Maintainable Software?Robby starts each episode by asking the guest what maintainable software is in their perspective.
Dan Langille: Moving local settings for pg_hba.conf and postgresql.conf out of PGDATA
One of the configuration aspects of FreeBSD I have long liked is the concept of default values which are overridden by the user. For example, /etc/defaults/rc.conf (see The /etc directory). The default values in this file can be overridden by the user with their preferred values in /etc/rc.conf (or /etc/rc.conf.local, and other locations if you so choose (search for rc_conf_files)).
semab tariq: Selective Column Replication in PostgreSQL
Discover selective column replication in PostgreSQL - a powerful feature for replicating specific columns across databases.

Andreas Scherbaum: FOSDEM and FOSDEM PGDay 2024 Review
FOSDEM 2024 in Brussels is history, and as always it was a good event and nice trip to Belgium.
PostgreSQL Europe did organize a PGDay on Friday before FOSDEM. In addition we had a stand at the main FOSDEM event, and a Devroom on Sunday.
Grant Fritchey: Functions and Procedures: Learning PostgreSQL with Grant
One of the most useful constructs in SQL Server is the stored procedure. It gives you a way to do several things. First up, you can store code within the database. Next, you can parameterize queries so that you’re not hard coding or generating ad hoc queries every time you want to call them. You can put in transaction handling, multiple result sets, security and more. They truly are a useful tool.
Raouf Chebri: PgBouncer: The one with prepared statements
The latest release of PgBouncer 1.22.0 increases query throughput by 15% to 250% and includes support for DEALLOCATE ALL and DISCARD ALL, as well as protocol-level prepared statements released in 1.21.0.

Henrietta Dombrovskaya: PG Day Chicago Schedule is announced!
Dea PostgreSQL Community, friends, and colleagues! The PG Day Chicago schedule is here! I want to thank everybody who submitted proposals and our CfP committee for doing an exceptional job reviewing submissions and finalizing selection in a very short time!
We will have three tracks with twenty-one talks total, plus Lighting talks, and my only regret is that I won’t be able to listen to most of them. But those who are going to attend will have way better chances!

Paul Ramsey: PostGIS Clustering with K-Means
Clustering points is a common task for geospatial data analysis, and PostGIS provides several functions for clustering.
Tristen Raab: Deciphering PostgreSQL Encryption: A Beginner’s Guide
In this blog, we’ll go over the different methods we can use to encrypt and decrypt data in a PostgreSQL database. Having some experience with Linux and PostgreSQL is necessary, while experience with encryption is not but is nice to have. This blog was written using PostgreSQL 16 running on Ubuntu 23.04. First I’ll go over some motivations for encryption and its importance to data security, then look at a subset of the functions offered by PostgreSQL to implement encryption.
Luca Ferrari: Using PL/Java to Return SETOF RECORD
A simple way to return multiple records from PL/Java
Using PL/Java to Return SETOF RECORDPL/Java allows a quite easy implementation of result set providers, objects that will produce rows that can be used as tables in queries. In order to produce a result set, the main steps are: 1) implement the ResultSetProvider interface and its method to effectively produce the data; 2) build a PL/Java function that will instantiate the above ResultsetProvider, so that PL/Java will wrap such function into a RETURN SETOF RECORD SQL function.
Ricardo Zavaleta: Benchmarking PostgreSQL connection poolers: PgBouncer, PgCat and Supavisor
Creating a connection to your Postgres database to execute a short-lived query is expensive. Several people have measured the overhead of Postgres connections and some locate them in the range of 1.3MB of memory per connection and others in the range of 2MB.
Vibhor Kumar: Exploiting SQL/JSON Enhancements for Modern Workloads in PostgreSQL 16
The latest iteration of PostgreSQL, version 16, brings a suite of enhancements that bolster its capabilities with JSON data. These improvements not only align PostgreSQL more closely with the SQL/JSON standard but also offer significant optimizations that streamline and enhance working with JSON data. This evolution is a testament to PostgreSQL’s commitment to meeting the demands of modern, data-driven applications that leverage semi-structured data for a myriad of use cases.
