Vacuuming is a key feature of PostgreSQL databases to keep databases healthy and optimized. For this, Autovacuum is configured to conserve space by removing obsolete disk usage, and to optimize database performance by speeding up sequential scans, just as one example. To discuss this topic in-depth, 2ndQuadrant hosted the “Postgres Vacuuming Through Pictures” webinar. The […]
PostgreSQL was presented with the 2019 O’Reilly Open Source Award for Lifetime Achievement in Portland, Oregon, Thursday July 18th during OSCON. I had the honor of accepting that award alongside Bruce Momjian and Christophe Pettus. Starting last year in 2018, these awards were presented to projects and the first Lifetime Achievement award was given to […]
Declarative partitioning got some attention in the PostgreSQL 12 release, with some very handy features. There has been some pretty dramatic improvement in partition selection (especially when selecting from a few partitions out of a large set), referential integrity improvements, and introspection.

The problem: duplicate rows Once upon a time, there was a database person who knows about referential integrity and its importance for creating database tables. The interesting part is that referential integrity, including primary keys, enable keeping with the standard of not having duplicate rows. However, they just wanted a private little table on their […]
PostgreSQL is packed with features. What may not be part of the core is available as extensions. What are extensions – you ask? PostgreSQL exposes APIs that are designed to easily allow external programs to load into the database and function just like core features. So if you find that you need a feature in […]
Docker Hub carries Docker images for PostgreSQL, based on Debian Stretch or Alpine Linux. These are not official PostgreSQL Development Group (PGDG) images from postgresql.org, they’re maintained in the Docker Library on Github. But as Docker adoption grows these are going to become more and more people’s first exposure to PostgreSQL. I tried these images […]
