Umair Shahid: Transitioning from Oracle to PostgreSQL: Partitioning
As databases grow, managing large tables becomes more challenging. Table partitioning is a tried-and-tested approach that helps break down large tables into smaller, more manageable segments, enhancing performance, maintainability, and scalability.

Luca Ferrari: PostgreSQL is super solid in enforcing (well established) constraints!
A note about mgirating from other databases…
PostgreSQL is super solid in enforcing (well established) constraints!Well, let’s turn that around: SQLite3 is somehow too flexible in allowing you to store data!
We all know that.
And we all have been fighting situations where we have a well defined structure in SQLite3 and, ocne we try to migrate to PostgreSQL, a bad surprise arrives! As an example, today I was trying to migrate a Django project with the built-in loaddata from a dumpdata, and sadly:

PGConf.EU 2024, held in Athens from October 22-25, was the biggest PostgreSQL event in the world yet! It was organized by:
Kaarel Moppel: Cloning Postgres user privileges vs ChatGPT
Andreas 'ads' Scherbaum: Rushabh Lathia
Sergey Pronin: Exposing PostgreSQL with NGINX Ingress Controller
Pavlo Golub: Introducing postgres-contrib.org and the PostgreSQL Event Calendar at PGConf.EU Lightning Talks
Floor Drees and Andreas Scherbaum took the stage during the PGConf.EU lightning talks to present postgres-contrib.org and the PostgreSQL Event Calendar! Slides are here
Deepak Mahto: PL/pgSQL Secrets: How Conditional Expressions Are Parsed and Evaluated Under the Hood.
Recently, in the Official PostgreSQL Slack, a user posted a PL/pgSQL block (shown below) and was surprised that it did not generate a syntax error:
DO $$ DECLARE i INT; BEGIN i = 0; IF i = 0 AND THEN RAISE NOTICE 'i = 0'; END IF; END; $$;At first glance, this code block seems incomplete. Notice the IF condition: it appears to be missing an additional condition after the AND operator. Logically, this should cause an exception due to the incomplete condition following AND.

I have pushed Release 18 of the PostgreSQL Buildfarm client
In addition to numerous minor tweaks and bug fixes, the following changes are made:
Robert Haas: Why pg_dump Is Amazing
I wrote a blog post a couple of weeks ago entitled Is pg_dump a Backup Tool?. In that post, I argued in the affirmative, but also said that it's probably shouldn't be your primary backup mechanism. For that, you probably shouldn't directly use anything that is included in PostgreSQL itself, but rather a well-maintained third-party backup tool such as barman or pgbackrest.
semab tariq: Offline PostgreSQL Installation on RHEL 9: Solving the No Internet Challenge
PostgreSQL is one of the most loved databases, especially by developers, for its simplicity, easy configurations, and massive community support. It's an open-source powerhouse known for handling everything from small projects to large-scale applications.
While major cloud providers, like AWS, Google, and Microsoft offer robust solutions for hosting databases on the cloud, not all businesses can or want to go this route

- On October 22nd the Extensions Ecosystem Summit took place, as an unofficial side event of PGConf EU in Athens. Supported by Tembo](https://tembo.io/), Percona, Xata, and Timescale, 5 speakers shared their (experience working on) extensions, followed by an open space / contribution fest meant to attract new contributors to the projects.
Christophe Pettus: An Interlude: Why you do not want to use C/POSIX locale.
(A quick interlude in our series on locales and character encodings in PostgreSQL.)
C/POSIX locale is only useful if you know that you will never have characters in your strings other than 7-bit ASCII, or you are 100% sure that you are never going to have mixed client encodings. If you do have non-7-bit-ASCII characters with mixed client encodings, zaniness can result:
Stefanie Janine: PostgreSQL in The Big Apple
For the first time we have a guest writer, Emma Saroyan.
Discovering PostgreSQL - My JourneyI recently traveled from Armenia to New York City to speak at PGConf NYC 2024, organized by PgUS. PostgreSQL, originally called Postgres, is the #1 open source relational database in the world. I gave a talk about my journey into discovering Postgres, and it was an inspiring experience engaging with the PostgreSQL community, sharing insights, and learning about the latest advancements in the field.
David Wheeler: PGConf & Extension Ecosystem Summit EU 2024
Last week I MCed the first Extension Ecosystem Summit EU and attended my first at PGConf EU in Athens, Greece. Despite my former career as an archaeologist — with a focus on Mediterranean cultures, no less! — this was my first visit to Greece.
