Elizabeth Garrett Christensen: Postgres Performance Boost: HOT Updates and Fill Factor
There’s a pretty HOT performance trick in Postgres that doesn’t get a ton of attention. There’s a way for Postgres to only update the heap (the table), avoiding having to update all the indexes. That’s called a HOT update, HOT stands for heap only tuple.

Hans-Juergen Schoenig: Enforcing join orders in PostgreSQL
After the pgconfeu23 in Prague – which has been an excellent event – I decided to share some of the things I presented as a blog post to maybe shed some light on some of those topics. One of those ideas presented was the way PostgreSQL handles joins and especially join orders. Internally the PostgreSQL does a good job to optimize queries but how does it really work?
Francesco Tisiot: How to use pgbench to test PostgreSQL® performance
Testing a database performance is a must in every company. Despite everyone's needs beings slightly different, a good starting point for PostgreSQL® database is using pgbench: a tool shipped with the PostgreSQL installation that allows you to stress test a local or remote database.
This blog post showcases how to install (on a Mac) and use pgbench to create load on a remote PostgreSQL database on Aiven.

Ryan Booz: Transforming and Analyzing Data in PostgreSQL
In our data hungry world, knowing how to effectively load and transform data from various sources is a highly valued skill. Over the last couple of years, I’ve learned how useful many of the data manipulation functions in PostgreSQL can supercharge your data transformation and analysis process, using just PostgreSQL and SQL.

Stefan Fercot: The importance of PostgreSQL timelines
Flashpoint: have you ever watched a Sci-Fi movie where the main character goes back in time, change something there (i.e. save his mother’s life) and then comes back to present days but arrives in an alternate reality? Applied to PostgreSQL backups, the alternate reality called timeline is a key notion for Point-in-Time Recovery.
