Craig gets you ready for production with this quick checklist of Postgres essentials.
Integer overflow can happen if you have a sequencing data type exceeding integer limits. Jesse has a query to help you spot it and recommendations for a short term and long term fix.
Unlogged tables in Postgres can give you a big performance improvement but beware of the drawbacks. Here are some tips on how to safely give it a try.
Go inside the WAL file with this in-depth look at WAL file Log Sequence Number (LSN), WAL segment positions, WAL file names, and pg_wal_switch.
Craig lays out four basic things to set up today to make finding and fixing performance faster in the future.
Enums or check constraints, which one is better? Craig breaks down why enumerated types aren’t common in Postgres.
Let’s show some love for the ANY Operator! Read about how to use = ANY(array) in place of the IN(list) so you can send all your parameters securely with prepared statements.
Jean-Paul shows some easy tricks for changing from Orafce functions to native PostgreSQL.
We just released a new version of Crunchy Postgres. Packed with security, access management, and monitoring updates. Giving you more flexibility and options for running production Postgres.
What happens when you query Postgres? Data can actually come from many different places like the application cache, buffer cache, and even down into the physical disk cache. This post surveys the data storage and flow of Postgres data.
Just kidding. This is not crypto mining tutorial! It is a very practical description of using pgcrypto for encrypting and decrypting data inside your Postgres database.
Checking on your collations is a must have stop on your migration path. You might just run a quick check and be on your way or you might need to add a few more steps to your cutover plans.
Seeing locks in your Postgres monitoring but don't know what it means? David takes a look at locks and what to take into consideration.
When it comes to database performance, many think they are solving technical problems, but are solving a money problem. There are 2 phases to database-cost management, and understanding which phase you are in will help you understand your options for growth.
Crunchy Data is excited to release a new open source tool, Exporter2Perfdata. This connects Prometheus Exporters with Icinga2/Nagios. This also allows pgMonitor users to connect monitoring information from Prometheus to Icinga2 and Nagios.
David optimizes a slow query by splitting up a left join into two calls and using UNION ALL to combine them. The proof is in the pudding.
Which of my applications ran this SQL statement? Use SQL comments to track which application ran which queries.
For developers, databases are basically magic. Like Penn & Teller, this blog post is set to break the illusion. Databases are just like any other code, they have algorithms and processes. These algorithms and processes are meant to improve performance, but can cause limitations if they are not expected.
Craig's year end wrap-up of 5 things you can do for a healthier Postgres database next year.
A deep dive into Patroni, etcd, and the etcd consensus protocol to diagnose common communication and system issues.
