Robert Bernier: Managing Time Series Data Using TimeScaleDB-Powered PostgreSQL

12. März 2024 - 15:05
PostgreSQL extensions are great! Simply by adding an extension, one transforms what is an otherwise vanilla general-purpose database management system into one capable of processing data requirements in a highly optimized fashion. Some extensions, like pg_repack, simplify and enhance existing features already, while other extensions, such as PostGIS and pgvector, add completely new capabilities.I’d like […]

Ryan Booz: Transforming and Analyzing Data in PostgreSQL

Stefan Fercot: The importance of PostgreSQL timelines

11. März 2024 - 16:28

Flashpoint: have you ever watched a Sci-Fi movie where the main character goes back in time, change something there (i.e. save his mother’s life) and then comes back to present days but arrives in an alternate reality? Applied to PostgreSQL backups, the alternate reality called timeline is a key notion for Point-in-Time Recovery.

When it comes to reordering the items in a list, databases have long had a kind of Faustian Bargain to accomplish the task. Nobody really liked any of the more common solutions, least of all the poor database tasked with serving up the inevitable resulting hack.

Postgres is no different in this regard. Consider a list_item table like this, demonstrating five items in a to-do list:

Invitation from Ryan Booz

Many of the PostgreSQL newbies that I’ve engaged with lately are coming from other databases often because of company priorities to start adopting Postgres and migrating projects. Inevitably, one of the first things they want to learn once data starts flowing is how to tune queries. They typically have a lot of experience doing this type of work previously, just not with Postgres.
