Neues vom PostgreSQL Planet

Earlier this year we started a program (“Developer U”) to help colleagues who show promise for PostgreSQL Development to become contributors. Meet Vaibhav Dalvi, Staff SDE, who, prior to joining EDB had no experience with databases! And now look at him!

Earlier this year we started a program ("Developer U") to help colleagues who show promise for PostgreSQL Development to become contributors. Meet one of the participants: Akshay Joshi, a Principal Engineer and Engineering Manager at EDB.

The PostgreSQL Buildfarm is a global network of machines that continuously test PostgreSQL across a wide range of operating systems, architectures, compilers, and branches. Over the past few years, I have created and maintained several buildfarm members, each with its own quirks and strengths. In this post, I’ll share a status-update working on the following animals: alligator, dodo,

In the past few months, two new database videos were released on YouTube. From Hollerith to Stonebraker, from IMS to Postgres, the first video does a great job of walking through the history of databases in a way that I have never seen before.

With 3k slides and 64 presentations (and more two pending), the Presentations section of my website was getting cluttered. (Okay, I guess it has been cluttered for a while.) I have restructured the sections, adding two, removing one, and moving superseded presentations to Old. Hopefully this will help website visitors more easily find useful information.

One of the temptations database users face, when presented with a huge table of interesting data, is to run queries that interrogate every record. Got a billion measurements? What’s the average of that?!

One way to find out is to just calculate the average.

SELECT avg(value) FROM mytable;

For a billion records, that could take a while!
