First off, there have been a few announcements over the past month or so worth mentioning.

Google announced on Nov 6: Cloud SQL for PostgreSQL adds high availability and replication.

Amazon announced on Nov 22: Amazon RDS Now Supports Database Storage Size up to 16TB and Faster Scaling for MySQL, MariaDB, Oracle, and PostgreSQL Engines.

Amazon announced on Nov 29 at reInvent: Serverless and Multi-Master (clustering) for Amazon Aurora.

Next, in the category of “battle stories with really useful information for everyone” there were two articles that got a lot of circulation and
stood out to us.

Pavan Patibandla from Amplitude published an article on Nov 22 which seemed to get a lot of attention on twitter: How a single PostgreSQL
config change improved slow query performance by 50x Michael Malis from Heap Analytics’ engineering team published an article on Nov 27 about Analyzing Millions of Postgres Query Plans. (This isn’t Michael’s first really interesting technical article about PostgreSQL either!)

In the category of “engaging articles about design & architecture” at least two recent articles stand out.

Stavros Korokithakis from Greece published an article on Nov 12 called “Startup Mistakes: Choice of Datastore” which was essentially about why you should not choose MongoDB.

Keith Alsheimer from EnterpriseDB published an article on Nov 21 called “Amazon RDS and Aurora: The Golden Arches of Postgres?” which was about how the heart and soul of PostgreSQL is its extensibility, and whether cloud-provided versions of PostgreSQL are worth the limits imposed on your ability to customize it.

Last but not least, the category of “stories and lore from PostgreSQL history”, you should definitely read Bruce Momjian‘s short article from
Nov 24 called “Postgres vs PostgreSQL”. Aren’t you wondering why Postgres/PostgreSQL has two names? Why nobody can make up their mind about which one to use? And WHY IS THE MASCOT AN ELEPHANT?! Read and learn!

About the Author

I have been in love with Oracle blogging since 2007. This blogging, coupled with extensive participation in Oracle forums, plus Oracle related speaking engagements, various Oracle certifications, teaching, and working in the trenches with Oracle technologies has enabled me to receive the Oracle ACE award. I was the first ever Pakistani to get that award. From Oracle Open World SF to Foresight 20:20 Perth. I have been expressing my love for Exadata. For the last few years, I am loving the data at Pythian, and proudly writing their log buffer carnivals.
