pgsql_tweaks is a bundle of functions and views for PostgreSQL

The soucre code is available on GitLab, a mirror is hosted on GitHub.
One could install the whole package, or just copy what is needed from the source code.

The extension is also available on PGXN.

Upgrading your PostgreSQL cluster is an important task to keep your database running smoothly and securely. With each new release, PostgreSQL introduces performance improvements, security patches, and new features that can benefit your system. However, upgrading can be a bit tricky, especially if you're working in a Windows environment, where certain challenges like permissions, service management, and file handling may differ from Linux setups.

In my last blog post, Evolution of Logical Replication, I mentioned the future development of a feature to allow "upgrades of logical replication nodes." The upcoming release of PostgreSQL 17 includes this feature. Previously, after major version upgrades (via pg_upgrade), users couldn't immediately connect and write data to logical replication nodes. This was because the slots were lost during upgrades, preventing replication from continuing.

The PostGIS Team is pleased to release PostGIS 3.5.0! Best Served with PostgreSQL 17 RC1 and GEOS 3.13.0.

This version requires PostgreSQL 12 - 17, GEOS 3.8 or higher, and Proj 6.1+. To take advantage of all features, GEOS 3.12+ is needed. SFCGAL 1.4+ is needed to enable postgis_sfcgal support. To take advantage of all SFCGAL features, SFCGAL 1.5 is needed.

A couple days ago I had a bit of free time in the evening, and I was bored, so I decided to play with BOLT a little bit. No, not the dog from a Disney movie, the BOLT tool from LLVM project, aimed at optimizing binaries. It took me a while to get it working, but the results are unexpectedly good, in some cases up to 40%. So let me share my notes and benchmark results, and maybe there’s something we can learn from it.

As I mentioned in my last blog post, as your cluster grows with multiple standby servers and potentially automated failover (using tools like Patroni), it becomes more practical to set up a dedicated repository host, also known as a dedicated backup server. This backup server can then trigger backups and automatically select the appropriate node in case of failover, eliminating the need for manual intervention.

The fifth Prague PostgreSQL Meetup of 2024 will take place on September 30th!

Introduction

As a senior database consultant and developer at CYBERTEC PostgreSQL International, I enjoyed speaking at PGDay Hyderabad 2024. This event marked two firsts for me: my first time visiting India and the first-ever PostgreSQL conference held in Hyderabad. I was filled with excitement and curiosity as I started this journey. I didn't know what to expect, but I was eager to experience it all.
