Andrew Atkinson: Maintainable Podcast — Maintainable…Databases? 🎙️

Neues vom PostgreSQL Planet - 19. Februar 2024 - 1:00

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

Neues vom PostgreSQL Planet - 18. Februar 2024 - 13:30

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)).

Grant Fritchey: Functions and Procedures: Learning PostgreSQL with Grant

Neues vom PostgreSQL Planet - 15. Februar 2024 - 23:09

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.

Tristen Raab: Deciphering PostgreSQL Encryption: A Beginner’s Guide

Neues vom PostgreSQL Planet - 13. Februar 2024 - 1:12
Introduction

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

Neues vom PostgreSQL Planet - 13. Februar 2024 - 1:00

A simple way to return multiple records from PL/Java

Using PL/Java to Return SETOF RECORD

PL/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.

Neues vom PostgreSQL Planet - 12. Februar 2024 - 22:56

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.

Andrew Dunstan: Review: PostgreSQL 16 Administration Cookbook

Neues vom PostgreSQL Planet - 12. Februar 2024 - 13:51

This book, published in December 2023 by packt, is the latest incarnation of a book originally principally authored by Simon Riggs, and brought up to date for PostgreSQL 16 by my EDB colleagues Gianni Ciolli,  Boriss Mejías, Jimmy Angelakos and Vibhor Kumar. It's available in both hard copy and electronic format. For review purposes, the publisher provided me with one of each. DBAs will probably find the electronic format more useful because of the ability to cut and paste from it.
