Managing another PostgreSQL Commitfest

October 15, 2019/0 Comments/in 2ndQuadrant, Alvaro's PlanetPostgreSQL, PostgreSQL /by Álvaro Herrera

I have written about managing a PostgreSQL commitfest before. During the PostgreSQL 13 development cycle, I did it again. This time I used a different strategy, mostly because I felt that there was excessive accumulation of very old patches that had received insufficient attention. So apart from bugfixes (which are always special cases), I focused […]

PostgreSQL 12: Foreign Keys and Partitioned Tables

October 14, 2019/4 Comments/in 2ndQuadrant, Alvaro's PlanetPostgreSQL, PostgreSQL /by Álvaro Herrera

Now that PostgreSQL 12 is out, we consider foreign keys to be fully compatible with partitioned tables. You can have a partitioned table on either side of a foreign key constraint, and everything will work correctly. Why do I point this out? Two reasons: first, when partitioned tables were first introduced in PostgreSQL 10, they […]

PostgreSQL 12: A Few Special-Case Performance Enhancements

September 24, 2019/2 Comments/in 2ndQuadrant, John’s PlanetPostgreSQL /by John Naylor

With every new release of PostgreSQL, there are a range of performance enhancements. Some are system-wide and affect every user, but most are highly specific to a certain use case. In this post, I am going to briefly highlight three improvements in PG12 that speed up certain operations. 1. Minimal decompression of TOAST values TOAST […]

PostgreSQL 12: Partitioning is now faster

September 17, 2019/4 Comments/in 2ndQuadrant, David's PlanetPostgreSQL /by David Rowley

Table partitioning has been evolving since the feature was added to PostgreSQL in version 10. Version 11 saw some vast improvements, as I mentioned in a previous blog post. During the PostgreSQL 12 development cycle, there was a big focus on scaling partitioning to make it not only perform better, but perform better with a […]

Partitioning enhancements in PostgreSQL 12

July 15, 2019/1 Comment/in 2ndQuadrant, Kirk’s PlanetPostgreSQL /by Kirk Roybal

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. In this article, we’re going to tackle the referential integrity improvement first. This […]

Computed columns in PostgreSQL 12 are here, but still have a ways to go.

Webinar: Migration to PostgreSQL [Follow up]

June 27, 2019/0 Comments/in 2ndQuadrant, Webinars /by Nouman

Among the many reasons to Migrate to PostgreSQL, available support is a key driver for many businesses deciding to migrate. PostgreSQL is an open source software which is also extendable. You can implement missing features in it as per your business need. Migration to PostgreSQL, however, can be a tricky decision as it requires planning, […]

Postgres-XL and global MVCC

April 2, 2019/0 Comments/in 2ndQuadrant, Koichi’s PlanetPostgreSQL, Postgres-XL /by Koichi Suzuki

Back to the PG I’m very excited to become a 2ndQuadrant member. I was involved in PostgreSQL activities in NTT group (Japanese leading ICT company, see here and here), including log shipping replication and PostgreSQL scale out solution as PostgresXC and PostgresXL. At NTT I had several chances to work very closely with 2ndQuadrant. After three years involvement in deep […]

Sequential UUID Generators on SSD

January 9, 2019/4 Comments/in 2ndQuadrant, Tomas' PlanetPostgreSQL /by Tomas Vondra

After I shared the sequential UUID benchmarks a couple of weeks ago, one of the points raised in feedback was the choice of the storage space. I’ve intentionally used a fairly weak storage system (RAID10 on three 7.2k SATA drives) because I wanted to demonstrate the benefits. But a couple of readers suggested using SSDs might significantly reduce […]
