At the time of this writing there were 123 members in the group. This level of response shows a great demand for Postgres content. I spoke …

PostgreSQL Non-exclusive Base Backups in Bash

Here I'm posting a bash script that implements PostgreSQL's new (since 9.6) "non-exclusive" base backup.

So I always try to steer people towards these binary "base backups", as they are called in the PostgreSQL …

Bridging the PostgreSQL Chasm

"I'm not technical enough to even understand what your firm does."

This message from a new LinkedIn connection last week. The message literally stopped me in my tracks. I was preparing to spend the day amongst new and seasoned developers at DevDay Austin, a free full-day technical event hosted by Amazon Web Services. Cloud computing, IoT, Containers, Artificial Intelligence, and Mobile application development were just a few of the …

The location was Adobe, next to Google and Tableau. I didn't even know there was a small tech complex on N. 34th in Seattle. There were about 27 people, which falls in line with the …

Postgres Load Testing with pgreplay

Overview

Usually we want to test before deploying changes to a production Postgresql cluster. Commonly the test itself is executed in a context that is not very similar to the production environment. How can you run a test that is realistic so there are no horrible surprises when you deploy on the production system?  Read on! This document describes a procedure where changes can be tested on a system that …

Postgres deferred PRIMARY KEYS, a hidden gem

Oracle 7.3 supports it!

That is how this all started. A gentleman tweeted about a Postgres limitation that Oracle has not had since at least since Oracle 7.3

The problem

As you can see in the tweet, Postgres by default will not defer a PRIMARY KEY check. Without the check being deferred the following will not work:

postgres=# select * from demo;
 id  
----
  1
  2
 (2 rows)
postgres=# …
