PostgreSQL maintenance doesn't have to mean downtime anymore. With pgEdge's zero-downtime node addition, you can perform critical maintenance tasks like version upgrades, hardware replacements, and cluster expansions without interrupting production workloads. Your applications stay online. Your users stay connected.

There is common misconception that troubles most developers using PostgreSQL: tune VACUUM or run VACUUM, and your database will stay healthy. Dead tuples will get cleaned up. Transaction IDs recycled. Space reclaimed. Your database will live happily ever after.

But there are couple of dirty "secrets" people are not aware of. First of them being VACUUM is lying to you about your indexes.

While moving production database workloads towards cloud-native (Kubernetes) environments has become very popular lately, plenty of users still rely on good old Docker containers. Compared to running PostgreSQL on bare metal, on virtual machines, or via a Kubernetes operator, Docker adds a bit of complexity, especially once you want to go beyond simple pg_dump / pg_restore for backups, upgrades, and disaster recovery.

In a recent Postgres patch authored by Greg Sabino Mullane, Postgres has a new step forward for data integrity: data checksums are now enabled by default.

This appears in the release notes as a fairly minor change but it significantly boosts the defense against one of the sneakiest problems in data management - silent data corruption.

Let’s dive into what this feature is, what the new default means for you, and how it impacts upgrades.

Postgres Ibiza (PGIBZ): An open source conference designed to bring together people with a love for PostgreSQL in Ibiza, a relaxed place for fresh and innovative discussions. An international event run by the nonprofit PostgreSQL España.

This was the first time that the Data Bene team attended the event, and we’re happy to share that it was a very positive experience.

The ClickHouse blog has a posted a piece by yours truly introducing pg_clickhouse, a PostgreSQL extension to run ClickHouse queries from PostgreSQL:

In this blog, we explore Postgres constraints through the pg_constraint catalog, covering table vs. column constraints, constraint triggers, domains and more.

In Part 1 we loaded our documentation into PostgreSQL. In Part 2 we chunked those documents and generated vector embeddings. Now it's time to put it all together with an API that your applications can use.

If you need to transition easily from Oracle to PostgreSQL without worrying about type conversions or other Oracle packages that require modifications to be PostgreSQL-compatible, a useful solution is IvorySQL!

There’s nothing simple about simplification! It is very common to want to slim down the size of geometries, and there are lots of different approaches to the problem.

We will explore different methods starting with ST_Letters for this rendering of the letter “a”.
