PostgreSQL:

Thanks to Jeremy Schneider for PostgreSQL links.

In the announcements category, it’s worth mentioning that on Dec 14 PostgreSQL 10 became Generally Available on Heroku.

With announcements out of the way, lets celebrate the season! There’s another great PostgreSQL story on SysAdvent this week – written by Kathryn Exline and published on Dec 12.

There have actually been quite a few great technical articles this week giving insight into how PostgreSQL works and how we can best use it. First, a great article from Robert Haas of EnterpriseDB on Dec 18 about MVCC and VACUUM.

Speaking of MVCC, I don’t think we ever mentioned this very visual write-up from October 22 by Diana Hsieh of Cockroach Labs about Handling Contention with PostgreSQL. MVCC is a critical concept in PostgreSQL and in all modern databases, so it’s worth the repetition!

Pat Shaughnessy writes a very in-depth post on Dec 15 explaining classic btree indexes and then Looking Inside Postgres at a GiST Index.

Getting a little more practical, Nathan Yergler from PlanGrid writes on Dec 15 with a great example of how to approach query tuning in his article Indexing with Postgres: When Less is More.

And finally, Emily Chang at DataDog pulled out all the stops and published a three-part series of articles about PostgreSQL monitoring. The articles really give a fantastic overview of PostgreSQL in general!

This should be more than enough reading for your holiday break!

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.
